海外TECH	DEV Community	Recursion in JavaScript and React Components	https://dev.to/dephraiim/recursion-in-javascript-and-react-components-352e	Recursion in JavaScript and React Components IntroductionRecursion in its essence is a method of problem solving that employs the solution to be expressed in terms of itself This means that a function that employs recursion will call upon itself repeatedly until it reaches a specific base case at which point the recursion will cease and the function will return a result Recursive functions can be very useful in a variety of situations They are a way of defining a function in terms of itself which can be a powerful tool for solving certain types of problems One example of where recursive functions can be useful is in computer science For example recursive functions can be used to traverse tree data structures allowing for an elegant and efficient solution to the problem of visiting and processing each node in the tree In this context a recursive function would call itself on each of the child nodes of the current node allowing it to visit and process each node in the tree in turn This approach can be much more efficient and elegant than using a loop to traverse the tree There are more practical applications of recursive functions as we would find out Let s look at some basic examples of recursive functions Factorial of a IntegerTo calculate the factorial of a number you simply multiply that number by every positive integer less than it For example to calculate the factorial of you would do the following x x x x Let s write a simple recursive function that will calculate the factorial of a numberfunction factorial n The base case if n is the factorial is if n return Otherwise the factorial is n the factorial of n return n factorial n Calculate the factorial of console log factorial Outputs The image shows the execution of the factorial function The factorial function calculates the factorial of a given number by calling itself repeatedly with the input number minus one each time This continues until the input number is at which point the function returns the base case and the recursion stops Fibonacci number at a given IndexA Fibonacci number is a number in a sequence of numbers where each number is the sum of the previous two numbers starting with and The nth Fibonacci number is calculated by adding the n th and n th numbers in the sequence For example to calculate the th Fibonacci number you would add the th and th numbers in the sequence and to get To calculate a Fibonacci number in Javascript you could write a recursive function like this function fibonacci n The base case if n is or the Fibonacci number is n if n n return n Otherwise the Fibonacci number is the sum of the previous two numbers return fibonacci n fibonacci n Calculate the Fibonacci number at index console log fibonacci Outputs This image shows the execution of the factorial function The fibonacci function calculates the nth number in the fibonacci sequence by calling itself repeatedly with the input number minus one and minus two each time This continues until the input number is or at which point the function returns the base case and the recursion stops The sum of the previous two fibonacci numbers are then returned allowing the recursion to return to the previous call and continue until the original call to fibonacci n returns the nth fibonacci number Sum of all elements in an ArrayGiven an array of integers you can use recursion to calculate the sum of all the elements in the array function sum arr The base case if the input array is empty the sum is if arr length return Otherwise the sum is the first element plus the sum of the rest of the array const firstElement arr const restOfArray arr slice return firstElement sum restOfArray Calculate the sum of the array console log sum Outputs The function calculates the sum of all the numbers in a given array by calling itself repeatedly with the input array minus the first element each time This continues until the input array is empty at which point the function returns the base case and the recursion stops The sum of the current element and the previous sum is then returned allowing the recursion to return to the previous call and continue until the original call to sum arr returns the sum of all the numbers in the input array Recursion in React ComponentsRecursion can be used in React components in cases where a component needs to render a nested structure of data such as a list of comments on a blog post or a social media site like Reddit Let s consider the following React component that renders a the comments and their replies like the one above function CommentThread comments return lt ul gt comments map comment gt lt li key comment id gt lt div gt comment text lt div gt comment replies amp amp lt CommentThread comments comment replies gt lt li gt lt ul gt The CommentThread component receives a comments prop that represents a list of comments and their replies The component renders a list with each list item representing a single comment If the comment has replies the component recursively renders a new CommentThread with the comment s replies as the comments prop This continues until all comments and replies have been rendered ConclusionAs you can see recursion can be a useful technique for solving a variety of different problems in JavaScript It s important to carefully consider the base case and the recursive step for each problem to ensure that the recursive function terminates and returns the correct result Recursion can also be computationally expensive and may not always be the most efficient approach Therefore it s important to carefully consider whether recursion is the right approach for a particular problem before implementing it in your code	2022-12-13 14:57:24

海外TECH	Engadget	The best robot vacuums for 2022	https://www.engadget.com/best-robot-vacuums-130010426.html?src=rss	The best robot vacuums for Robot vacuums have come a long way over the past few years They re smarter more powerful and marginally better at avoiding chair legs than they ever were before and you don t have to shell out as much money to get one either There are also many more robo vacs available now than there once were so deciding which to buy isn t as simple as choosing the latest model from the biggest brand We tested out many of the newest models available now to see how they stack up against each other and to help you choose the best robot vacuums for your needs Are robot vacuums worth it We tackled this question in our budget robot vacuum guide and the answer is yes especially if vacuuming is one of your least favorite chores Robots take the hard work out of cleaning your floors just turn the thing on and watch it go Any robot vacuum cleaner worth buying is semi autonomous in that it will suck up dirt around your home until its battery is low and then make its way back to its charging dock You should only have to interact with it to turn it on empty its dustbin and untangle it if it were to get stuck somewhere That s not to say robot vacuums are perfect They re almost always less powerful and less flexible than standard vacuums Since most robo vacs are much smaller than traditional models they often don t have the same level of suction you ll get in an upright machine Plus their dustbins are smaller so they will need to be emptied more frequently While WiFi connected robot vacuums give you the flexibility to start a cleaning job from anywhere using an app targeting a small area of your home can be more complicated Some robo vacs have spot cleaning features that focus the machine s attention on a specific area which almost but not quite mimics the spot cleaning you d be able to do yourself with a regular or cordless vacuum What to look for in a robot vacuumiRobt AccuSoft Co All rights reservedAs we explained in our budget guide WiFi is a key feature for most robot vacuums Some of the cheapest devices aren t WiFi connected though so if you re looking at the most affordable devices it s best to check for that feature before you buy WiFi connectivity allows a robot vacuum cleaner to do things like communicate with a mobile app which then allows you to control the device from your phone Suction power is another important factor to consider Unfortunately there isn t a standard power scale that all robo vacs adhere to so it s difficult to compare suction power among a bunch of devices Some companies provide Pascal Pa levels and generally the higher the Pa the stronger the vacuum will be But other companies don t rely on Pa levels and simply say their robots have X times more suction than other robots Ultimately we recommend thinking first about the floors in your home Do you have carpet throughout or tile and hardwood floors or a mix Robots with stronger suction power will do a better job cleaning carpets as they can get into the nooks and crannies more easily Some machines have “max modes as well which ups the suction power but also typically eats at battery life faster than the “normal cleaning mode Past a certain price threshold you ll find advanced features like home mapping improved object detection and automatic dustbin disposal Home mapping is exactly what it sounds like The vacuum uses sensors to map your home s layout as it cleans allowing you to send it to particular rooms or areas in later cleaning jobs Most robo vacs have some version of object detection but some will be better than others at actually avoiding things like chair legs and children s toys Some like iRobot s j series even go so far as to promise to avoid things like pet poop that can potentially ruin your machine Finally for peak convenience consider a robot vacuum that comes with a clean base These are basically garbage bins that are attached to the machine s charging base At the end of each job the robo vac automatically empties its small dustbin into the large clean base that means you won t have to empty the dustbin yourself and you ll only have to tend to the base once every few weeks Just keep in mind that most clean bases require proprietary garbage bags another long term expense you ll have to factor into the cost of owning one of these devices Best midrange robot vacuum Shark AI Robot Vacuum with BaseShark s RVAE AI robot vacuum with Base ticks all of the boxes that a mid range machine should It offers reliable cleaning performance its mobile app is easy to use and it produces accurate home maps On top of that its base is bagless which means you won t have to spend money every few months on garbage bags for your robotic vacuum Setting up the Shark is as simple as taking it and its base out of the box plugging the base in and downloading the companion mobile app to finish things up The machine connects to WiFi allowing you to control it via the app when you re not at home or using Google Assistant and Alexa voice commands The first journey the Shark makes is an “Explore Run during which it produces a map of your home that you can then edit from the mobile app The Shark produced a pretty accurate floorplan of my two bedroom apartment and I was happy to see a “re explore option that I could use if the map wasn t up to my standards With a completed map you re then asked to label rooms in your home That way you can send the Shark to only the bedroom for more direct cleaning jobs select “no go zones and more The first few times I ran the Shark robot I had it clean my whole apartment I was impressed by how quiet it was or rather how much quieter it was compared to other robo vacs I ve tried You ll have to turn up the volume on your TV if it s cleaning in the same room but it ll be hard to hear when it s sucking up debris down the hallway It also did a decent job maneuvering its way around the cat toys I left out on the floor The device s object detection feature claims it can avoid things as small as four inches but I found that it was much better at sensing and moving around the three foot long cat tunnel on my floor than the many tiny mouse toys But even if Mr Mouse caught the edge of the Shark s wheels now and then the robo vac took it all in stride One thing I look for when testing robot vacuums is how much attention they need from me during cleanings The best ones require no extra attention at all once they start a job they re smart enough to putter around your home move around objects and return to their base when they re finished With Shark s robo vac I never had to tend to it when it was cleaning Now I did my due diligence and picked up pieces of clothing and charging cables off the ground before running the Shark ditto for every other robot vacuum I tested so those things were never in the way Most companion apps will actually remind you to do this before starting a cleaning job This Shark machine comes with a clean base so it will empty its dustbin after every job and also during a job if its bin gets full before it s done In the latter situation the Shark will go back to cleaning automatically after it s freed up its bin That s a great feature but I found the best thing about the base to be its bagless design Shark s device is unlike most other robot vacuum clean bases because you don t have to keep buying proprietary garbage bags to outfit the interior of the base When you want to empty the base part of it snaps off and opens to eject debris and it easily locks back in place when you return it Not only is this quite convenient but it also brings the lifetime cost of ownership down since you won t be buying special bags every few months Its worth noting that Shark has a couple of models that are similar to the RVAE that just have a different color scheme a versus day clean base capacity and other minor differences The biggest feature that would impact how you use the machine is the clean base capacity we recommend springing for the day models if you want to interact as little as possible with your robo vac Runner up midrange Roomba jNot much has changed since Amazon bought iRobot a little while back the Roomba j remains a great option if you want the latest obstacle avoidance technology from the company in an attractive package The j doesn t come with a clean base but you can get the same vacuum with one for extra The biggest selling point of the Roomba j series is its upgraded AI driven computer vision which helps it detect and move around objects This includes pet poop a robot vacuum s arch nemesis and iRobot even promises that it will replace your j machine if it runs into pet poop within the first year of ownership That s one feature I was happy I never got to test as my cat kept all of her activity to her litter box Otherwise the Roomba j did a good job sucking up dirt and debris around my apartment and it didn t make too much noise while doing so All of the robo vacs I tested at this mid range level had roughly the same level of suction so there wasn t a big difference between them when it came to cleaning power Like other robot vacuums you can set cleaning schedules in the iRobot mobile app so you never have to start a cleaning job on the fly The app also has a “favorites section which lets you create profiles that you ll use all the time like “clean the living room and the entryway And if you prefer to use voice commands the robot supports Amazon s Alexa and the Google Assistant The Roomba j has Imprint Smart Mapping but unlike the Shark it took more than one runthrough of my home for it to create a complete map iRobot s app distinguishes between a regular cleaning job and a “mapping run so make sure you re choosing the latter the first few times you run the machine I tested the j which means I was treated to the roaring sounds of the machine emptying its dustbin into its clean base The emptying process isn t as simple as an automatically opening flat that shakes dirt from one garbage can to another the base actually sucks the dirt from vacuum This was the case for all of the machines I tried that came with clean bases they re all quite loud but the Roomba j was the loudest of them all The whooshing sounds last for only five to seconds but it was shocking the first time it happened Just keep that in mind if you ever decide to run the robot at night when others are sleeping Honorable mention Anker Eufy RoboVac X HybridYou may be unfamiliar with Anker s robot vacuums but they re often more affordable alternatives to the iRobots and Sharks of the world The Eufy RoboVac X Hybrid isn t a budget machine by any means but it s a solid robot vacuum that offers a few key features that many competitors don t have Plus you can often find it on sale for or even Unlike our other midrange picks the X Hybrid doesn t come with a clean base nor is there one you can purchase separately It s just a standalone robo vac but the “hybrid indicates that it s also a robot mop It has both a dustbin for collecting debris and a milliliter water tank that you can fill whenever you want to run a mopping cycle Plenty of other robot vacuums have this feature and it could be even more useful than a clean base if you have lots of tile or hardwood floors throughout your home Besides that I was impressed with how easy it was to set up the X Hybrid how accurate its mapping technology was and how many extra features it supports It has four cleaning modes auto room zone and spot and four suction levels starting with Pure at the low end and topping out at Max These features give you a lot of control over where the machine cleans and how powerfully it will do so The X Hybrid was in Pure mode the first time I ran it and I was surprised by not only how quiet it was but also how thoroughly it cleaned considering it was on the lowest suction setting There s also a “tap and go feature that lets you pinpoint any spot on your home map in the EufyHome app sending the robot there to clean Manual controls are also available which isn t something you see on a ton of robo vacs This option lets you control the machine almost like a slow and slightly clumsy RC car giving you more control over where it cleans It may not have the name recognition that iRobot or Shark do but the Eufy RoboVac X Hybrid is a solid choice nonetheless especially if you don t care to add a clean base into the mix It s an even more tempting choice if you can snag it when it s discounted Best premium robot vacuum iRobot Roomba s The Roomba s is admittedly overkill for most people but it s nothing if not one of the best robot vacuums out there You ll notice its premium features as soon as you unbox it The s is the biggest but also the most attractive robo vac I tried with a corner friendly design copper accents and a foot tall clean base The setup was quick and easy with the machine taking only a few minutes to connect to my home s WiFi and the iRobot app While the s doesn t have the Precision Navigation feature that the newer j does it has something called “Careful Driver that uses a D sensor to detect and clean around objects It seems that the main difference is that the s isn t specifically wired to avoid pet poop so keep that in mind if you have furry friends around the house However with x the suction power of a standard Roomba the s does a great job cleaning up pet hair It s also louder than the j when it s cleaning but not irritatingly so and I noticed a deeper clean in my carpets thanks to the extra suction And it changes its cleaning mode automatically when transitioning from say carpeting to a hardwood floor Even this robot vacuum bumped into a few table legs while cleaning but it was noticeably better than other machines at navigating around my furniture and correcting itself when it got stuck It also moves faster than the j so it was able to cover a bit more of my apartment before it had to return to the base for charging after about one hour of cleaning I was also pleasantly surprised to find that the s wasn t nearly as loud as the j vacuum when emptying its dustbin into the clean base With the iRobot app experience being the same across all Roombas the s stands out for its subtle premium features like its elegant design elegant looking clean base superior cleaning intelligence and top of the line suction power Aside from the extra suction those are all nice to haves rather than must haves so most people including you probably don t need the Roomba s It s the fanciest robot vacuum iRobot has to offer but you ll get a similar level of quality with the Roomba j while spending a couple hundred bucks less Honorable mention Roborock S Roborock s high end S deserves a mention for its cleaning power and number of additional features that many other competitors don t have First the S is a vac and mop combo and its mopping map automatically lifts itself out of the way when the machine reaches the carpet That means you can have it clean your whole home vacuuming and mopping in the right spots without you giving it any extra attention besides filling its ml water tank at the start The expensive machine has a longer setup process because its clean base comes in two pieces You must attach the bottom of the base where the robo vac charges to the garbage bin upper portion using a few screws and a tool that attaches to the bottom of the base Roborock provides everything you need to do this in the box so while it takes a bit more time it s still an easy process What wasn t so easy for me at first was connecting the S to the Roborock app The vacuum had trouble connecting to my home s WiFi network but I was able to connect it to the Mi Home app which is Xiaomi s main smart home companion app Xiaomi is an investor in Roborock There aren t a ton of differences between the two apps when it comes to robo vac controls but the S is designed to work with Roborock s program After troubleshooting with a Roborock representative I was able to fix the problem by factory resetting the vacuum and that allowed me to connect it to the Roborock app properly That said the Roborock app isn t nearly as polished as those from iRobot Shark and others The main page shows your home s map along with the battery level cleaning time cleaning area in feet and buttons that let you quickly start a cleaning job and empty the dustbin You re also able to select specific rooms or zones to clean but the rest of the control options live in the menu accessible by the three dot icon at the top right corner of the app Things are a little buried and that might make the S harder for robot vacuum newbies to use When it comes to cleaning performance the Roborock S did a great job sucking up dirt around my home In addition to the usual features like cleaning schedules zone targeting and others the vacuum also has things like child lock which will disable the physical buttons on the machine different auto emptying settings to choose from “pin and go which lets you tap on your home map to send the robot to a specific location and manual direction controls so you can move the machine like a toy car This isn t the robot vacuum to get if you want the most polished experience and you may very well want that if you re dropping on one but it remains a powerful vac and mop machine with a handful of extra perks Best budget robot vacuum Roomba iRobot s Roomba is a great option for most people thanks to its good cleaning power and easy to use mobile app We won t get too deep into it here since we have a whole guide to affordable robot vacuums with additional recommendations But suffice to say the gives you all the essentials you d expect from a robot vacuum along with all of the convenience that comes with iRobot s mobile app	2022-12-13 14:25:08
