海外TECH	DEV Community	Sieve of Eratosthenes, What is it?	https://dev.to/codereaper08/sieve-of-eratosthenes-what-is-it-2o3g	Sieve of Eratosthenes What is it Image source famousmathematicians net What is it Sieve of Eratosthenes is an algorithm devised by the Eratosthenes of Cyrene It does the job of finding all the prime numbers within a given upper limit This ancient algorithm is efficient and smart till the upper limit is a few billions So we ll discuss the process and JavaScript code for the same below How it works The algorithm starts with generating a list of all numbers starting from to n where n is the upper limit with the assumption of all the numbers in the list are prime It starts from and removes all the multiples of in the list by traversing the list in the interval of So now we consider n as let sample array Starting from it removes the multiples of by traversing the above list in a step count of Note below means removed from list let sample array After removing all the multiples of we move to the next non removed number that is now from we traverse the list with the step count of and remove its multiples let sample array We then proceed to the next non removed number which is But here s the thing the multiples of are already removed from the list We just make sure when to end this cycle of traversal and removal by calculating the square of that is which is obviously greater than n that is So we stop the process and get the remaining elements which are prime Here s the final list we get let sample array Hurray we ve done with the theory part let s get our hands dirty with some JS to actually code it Execution in JS Let s start by creating an empty array called Boolarray why naming Bool because we are going for a Boolean array We also initialize the value of n as let Boolarray let n Remember we first made an assumption that all the numbers in the list here array are prime So we use true for is prime and false for not a prime with this in mind we first fill the empty array with boolean values of all True based on our assumption We use a for loop with iterator i to iterate from to n and fill the array with True let Boolarray let n for var i i lt n i Boolarray push true Now we have an array of length with true on all indexes We now follow the procedure of Sieve of Eratosthenes by starting the for with iterator j from to j j lt n j j lt n checks when to end the looping If the current element in the array is true we then loop over its multiples with iterator kand a step count according to the current element and mark them false let Boolarray let n for var i i lt n i Boolarray push true for let j j j lt n j if Boolarray j true for let k j k lt n k j Boolarray k false After this execution we are left with a Boolean array which contains true in places of prime remember true →is prime and false in places of non prime numbers in the array Now it s all logging it onto the console We use another for loop to iterate on Boolarray with iterator num starting from to num lt n We console log only the num s which contains true in the Boolarray for let num num lt n num if Boolarray num true console log num So we end with this final code You can also use the JSFiddle to change the hard coded input n to your wish JSFiddle link Attributions Cover image Photo by Jaanam Haleem on Unsplash Thanks for reading Feel free to correct and give feedbacks Like it then it	2021-07-21 18:52:40
海外TECH	DEV Community	Regex 101	https://dev.to/shreyazz/regex-101-2m7m	Regex Hey readers in this blog we are going to talk about Regular Expressions or we can also call it REGEX REGEX is sequence of characters which are in a certain patter and these patterns help us find or find and replace or validate things like email passwords and usernames Let s start learning ‍   Basics The most easy way to explain regex with an example is if we want to search the word JavaScript in a string Now this example is very basic but believe me REGEX has lots and lots of use cases   Multiple Possible Characters Let s see an example where you want to see if the string contains many possibilities for example if you want to search for dog or cat We can do this by using the OR sign Here if the petString would contain Shreyas loves JavaScript then the output would have been false To be clear the REGEX patterns are case sensitive so if a string would contain shreyas and I search for ShreyaS then the output would be false   Case Sensitiveness What should we do when we are not sure about the case No worries We can make our REGEX Pattern ignore the case As you can see we have used i in regex and there are many such flags which gives us a lot of control over the pattern i stands for irrespective of the case Here we are using test method which is an inbuilt method in JavaScript which returns true or false according to the pattern entered The Syntax is pattern test String which has to be tested   Global Searching test has a draw back which is that it only returns true or false and if true it does not tell us how many times the pattern was matched so to back this drawback JS has another inbuilt method called as match which let s us know how many times the pattern is matched in the string match return an array of results which have successfully matched the pattern and the array s length is the time the pattern was recognized Let me show an example Here you can see the syntax of match is a little bit different when compared to test match s syntax is string match regex pattern Also you can see that I have used another flag which is g and it stands for global which helps us find the perfect match globally in the string   Find Group of Letters We can group many letters together to find them inside a string REGEX gives us flexibility with Character Classes these allow us to define a group of characters and they have to be enclosed in Square Brackets It will be more clear when you see an example We have to find every vowel inside a string The pattern has flags which are non case sensitive and to check globally in the string Here aeiou vowels are grouped together and are individually searched in the string   Match anything using Wildcard period dot Some times we just have to search for words which end with some certain letters or which start from some certain letters To do so we have wildcard period which is basically a period dot If we have to match words which end with the letters un For example fun or run or sun For that we have This pattern will check for any word ending with un and it will do it irrespective of the case i flag and would search in the whole string g flag   Range of Characters We can also provide a range of characters to check from For Example If you are sure that there are possibilities that the word may start with any character but the ending will be with the letters at then we can give a range of characters which will check the string and if matched then return an array Note If no value is found NULL would be returned   Match Numbers What if you wanna match numbers Don t worry REGEX has got you covered Just like characters we can write g that s it all the numbers are covered But as we all know us developers we are lazy So why to write when you can also write d g and this d stands for digits   Match Number and Characters To match number and characters we can write But isn t this REGEX Pattern too long We have a shorthand for this which is w g and instead of the whole REGEX pattern you can just write the shorthand   Check for Minimum and Maximum Characters We can set a min and a max amount of characters This REGEX pattern allows only those strings which have equal or greater length then and are under or equal to The syntax for that is regex here min number max number g Challenge I wanna give a quick challenge to all the readers why don t you make a REGEX which verifies usernames and the conditions are Username should have numbers Username can have an underscore Username should not have any special characters Username should have minimum characters and maximum characters Thank you so much for reading the whole blog if you liked it do share it with your friends and implement REGEX in your upcoming projects It has saved me from writing lots of line of code and a lot of time too I am sure it will be very effective for you too Till the next blog Goodbye	2021-07-21 18:01:56
