海外TECH	DEV Community	7 JavaScript Concepts You Should Be Familiar With As a Developer	https://dev.to/vivaluv/7-javascript-concepts-you-should-be-familiar-with-as-a-developer-3oc0	JavaScript Concepts You Should Be Familiar With As a DeveloperAs of JavaScript currently stands as the most commonly used language in the world It is used by percent of all websites whether small startups or giant corporations Several of them are working on specific website or app that requires a strong understanding of this language There are tons of frameworks and libraries available for javascript users If you can understand Javascript fundamentals you can learn these frameworks and libraries easily Several concepts are confusing and overwhelming for several developers but learning these Javascript concepts will benefit you in the long run Not only that but learning these JavaScript concepts will help you build any kind of application and learn any framework and libraries Learning Javascript is going to come in handy to you in It will also help you in interviews as well So without further ado let s discuss some fundamental Javascript concepts that every JavaScript developer should know ScopeScope stands for variable access So the question is what variable do I have access to when a code is running However in Javascript you are always in the root scope by default the window scope These boundaries restrict variables and determine whether or not you have access to them It restricts a variable s visibility or availability to other parts of the code Understanding this concept will help you separate logic in your code and improve readability We can define a scope in two ways Local Scope It lets you access everything within the boundaries inside the box Global Scope It lets you access everything outside the boundaries outside the box It can t access a variable defined in the local scope unless you return it as it is enclosed from the outside world Async amp AwaitAsync amp await are essentially syntactic sugar on top of Promises and they give the means to keep asynchronous operations running more synchronously just like Promises As a result you can handle asynchronous operations in javascript in several ways ES gt CallbackES gt PromiseES gt Async amp AwaitIn cases where you wish to wait for the data to fully load before displaying it you can perform a Rest API request using Async Await They are great syntactic improvements for NodeJS and browser programmers It helps developers implement functional programming in Javascript and also makes the code more readable CallbacksWhen a function is called it must wait for another function to perform or return a value creating the chain of functionalities As a result callbacks are generally used in javascript s asynchronous operation to provide synchronous functionality ClosuresSimply put a closure is a function within another function with access to the outer function variables The definition itself seems pretty straightforward but the scope makes this definition unique Inner functions closure can access variables defined in their scope variables defined between curly brackets their parent functions and inside global variables Now here you need to keep in mind that the outer function cannot have access to the inner function variables HoistingSeveral developers get unexpected results because they are unfamiliar with the concept of hoisting in javascript If you call a function before it is defined in javascript you won t get an Uncaught ReferenceError error As a result the javascript interpreter elevates variables and function declarations above the current scope function scope or global scope before executing the code IIFE Immediately Invoked Function Expression As its name implies IIFE is a Javascript function that immediately gets invoked and executed instantly as it is defined A variable declared within IIFE cannot be accessed by the outside world preventing the global scope from getting polluted Thus IIFE is primarily used for the instant execution of code and data privacy PromisesPromises are useful in asynchronous javascript operations when you need to start two or more back to back operations or chain calls where each subsequent function is called after the preceding one finishes A promise is an object that will produce a single value shortly either a solved value or a reason why it cannot be resolved rejected A promise can exist in one of three states Fulfilled Operation completely successfullyRejected Failed operationPending early state neither fulfilled nor rejected Thanks for taking your time to read this article	2022-11-29 03:31:36
