海外TECH	DEV Community	Building Iterators	https://dev.to/dnafication/building-iterators-1ebb	Building IteratorsAs programmers one of the very first thing we learn is the loop There is always an array or list or collection which needs to be looped through an object or map or dictionary whose keys and values require traversing Iterations are key programming concept Arrays and Maps are collections of things and it should to be defined explicitly prior to iterating You can start out with an empty array or a declaration and you can push items to it Example const things headphone keyboard mouse const friends tomo nuxt expert jt writes nasty sqls deco the leader van php guru things push cables one of the ways of iterating arraysfor const thing of things console log thing iterate the key of objectsfor const name in friends console log name friends name There are many ways of iterating over an array or an object To name a few for const i i lt arr length i for of MDNfor in MDNwhile MDNArray forEach MDNArray map MDNArray filter MDNArray reduce MDNOne thing about arrays or objects Map Set etc is that you kind of know what you are getting You could push things into an array but you know what you pushed Its not dynamic If something is in array its there for good until you remove it Also its taking up that space in the memory Iterator protocolWhat if you had a dynamic array that calculated what value you get in the next iteration What if that worked based on a formula that you ve built You need to use iterator pattern You ll notice that its very simple to implement Its a protocol that is well known among JS programmers and also followed in other languages too An iterator is an object that has next method Calling next function on the object gives us the iterator result which is an object with two properties done which is a boolean to hold the status of the iterator and value to hold whatever you want to return Let s build a simple range iterator This range iterator will allow us to create a range of numbers by providing a start end and step iterator protocol an agreed interfacefunction numberRangeIterator start end step let index start return next if index gt end return done true value thanks for using me value is optional here but you can use it to return meta info const value index index step return done false value const iterator numberRangeIterator let iteratorResult iterator next while iteratorResult done console log iteratorResult value iteratorResult iterator next You see Its very simple and yet powerful Two things to note the next function should return and object with done true to indicate that there are no more elements But it s not mandatory you can have an iterator that runs forever you can have done false or return just value and above code will just work fine function randomNumberIterator return next return done false value Math random const rIterator randomNumberIterator let rIteratorResult rIterator next while rIteratorResult done console log rIteratorResult value rIteratorResult rIterator next While I cannot think of when you d use the iterator above I just wanted to demonstrate an iterator that can generate random numbers infinitely Iterable protocolIterable protocol goes one step further by defining a standard within JS language for any object to return an iterator An iterable is an object that implements an iterator method called Symbol iterator The best thing about using iterables over the iterator which we talked about above is that it allows us to use JS native apis for looping over the array such as for of Let s build our numberRangeIterator as an iterable class NumberRange constructor start end step this start start this end end this step step for an object class to classify as iterable it has to implement Symbol iterator Symbol iterator let index this start return next gt if index gt this end return done true const value index index this step return value const myRange new NumberRange for const num of myRange console log num It was almost the same amount of code to define the iterable class and we reused most of our code However the beauty is in the way we consume the iterator Using for of makes it look so clean and concise I prefer this over the while loop above But it doesn t stop here There are other ways you can consume this iterable You can use it with spread operator const myRange new NumberRange console log myRange prints Or destructure and assign itconst myRange new NumberRange const first second third myRangeconsole log first second third prints There are other JS built in APIs that accept iterables where you can pass your iterables such as Array from iterable Set iterable Promise all iterable and even stream Readable from iterable Read more about iterators here You can pretty much treat it like your regular array but dynamic in nature and it will calculate your values only when it needs to Things get a bit hairy though when you start getting into the territory of async iterators but that is for another day	2022-04-04 01:36:06

海外TECH	DEV Community	Technical Guide To Getting Started in Data Science	https://dev.to/mukumbuta/technical-guide-to-getting-started-in-data-science-3map	Technical Guide To Getting Started in Data ScienceIn this guide “The Ultimate Guide to Getting Started in Data Science we will explain more about How to get started in Data Science What does a Data Scientist do Data science is the study of how to use advanced analytics and scientific principles to get valuable information from data for business decision making strategic planning and other purposes such as making better business decisions To begin with Data Scientists need data It could be finance healthcare sports government industry research entertainment or software engineering everyone is producing more and more valuable data Data is so valuable to businesses because it tells them what people want or need Besides it tells exactly who likes their product when they re buying it how they re buying it how often they re buying it A data scientist s job is to turn simple raw and unprocessed data into an information gold mine Essentially data scientists take an ugly big pile of messy data and turn it into a polished conclusion that everyone can understand Then they give recommended actions to take based on their conclusions Below is step by step guide on how to get started in data science STEP Learn a Programming LanguageFirst things first if you want to becoming a data scientist you must learn a programming language To help you with choosing a programming language among so many here are a few but useful tips SUPPORTIVE You want to make sure there s a big community for it which you can turn to for advice like on stack exchange POPULAR You want lots of pre written code libraries that you can integrate into your own code like on github This way for example you don t have to understand how to create a graph from scratch you can just select the graph you want and feed in your data EASY You also want a language that s easy to write in so you don t make little mistakes that then result in bugs you may spend hours trying to find This means it s very easy for you and others to review what you ve done FAST You want to be able to write programs fast You want to spend your time analyzing the data not writing code The faster the programming language lets you create prototypes the better POWERFUL You want to have the option to do long and complex tasks that still run fast and that can be easily integrated into other platforms Considering these qualities the most common programming languages used by data scientists are Python and R Some other viable ones are JavaScript C Matlab and SAS Of course if you feel more comfortable using another language by all means do so at the end of the day whatever you re fastest in and most comfortable with is what s best for you So now that you have the skills to make your computer crunch data visualization will set you up to do great analysis and creating comprehensive reports Step Make Graphics Your New Best FriendsVisualizations serve two purposes for a data scientist They let you analyze data more easily They make it much easier to communicate what you ve done with othersVisualizations play a very important role during your analysis because they let you literally see how your data behaves The more you do this the better you ll get at being able to differentiate true information signal against ones that are just produced through chance noise So as a data scientist you ll be creating the visualizations both to help guide your analysis as well as to visualize results Once you ve completed your analysis if you have to create a report or presentation you can then pick out the ones that actually say something valuable So how can you practice creating and reading these types of graphs Matplotlib as an amazing library for Python is the answer and a must know for every aspiring data scientist So I d highly recommend learning to use that to start making visualizations Step Learn How to Analyze DataA good thing to learn alongside of creating and reading the above types of graphs is how to analyze data The only way to properly analyze data is to be able to filter group drop aggregate or manipulate it in other ways Otherwise you won t be able to correctly control and contextualize your analysis or have the ability to zoom in when answering very specific questions Fortunately Python also has an amazing library for data analysis called Pandas that you can just freely download and then use in Python You can probably start to see why I like Python so much As a data scientist you re going to need data That data is usually stored in a database Therefore you ll need to learn how to interact with a database The most common database type you ll encounter is an SQL based database There are very many different databases that are based on SQL such as PostgreSQL Big Query or MySQL SQL databases are also very nice to use because it will speed things up a lot when you start processing formatting or even doing part of your analysis in your query rather than taking out the data and doing all of it afterwards Did you follow the steps above Boom You re a Data Scientist	2022-04-04 01:09:20
