DevBlogs·4yA Proposal For Type Syntax in JavaScript
A proposal to bring optional and erasable type syntax to JavaScript. Because this new syntax wouldn’t change how surrounding code runs, it would effectively act as comments. We think this has the potential to make TypeScript easier and faster to use for development at every scale. We’re hoping to bring it forward in a proposal to TC39.
SNIPCART·4yThe 6 Best JavaScript Frameworks to Use in 2022

Medium·4yWhy does JavaScript’s parseInt(0.0000005) print “5”?
The parseInt(string, radix) function parses a string argument and returns an integer of the specified radix (the base in mathematical numeral systems) The first step is to convert the number to string and the second step is the rounding operation. The answer will return 5 only because it is the only character that is a number till a noncharacter e, so the rest of it e-7 is discarded.
asayer·4yIntegrating Axios with React Hooks
React Hooks provide a simple, functional way of building stateful components. They can be used to wrap different APIs or digestible functions. In this article you’ll learn how to use Axios as well as how to build a comfortable wrapper around it. Axios is one of the most popular HTTP JavaScript client libraries.
Dev Genius·4yAsynchronous Javascript Practical Explanation
I will explain synchronous (sync) and asynchronous (async) in practical terms only. In synchronous process we do tasks one at a time. In asynchronous process, if we ever encounter long task which do not require our full attention, instead of waiting for the task to be completed, we do other stuffs first. I will use NodeJS to run Javascript as examples in this story.
Bits and Pieces·4yDeveloping a Small World in Three JS

Developing a 3D world using the Three JS library is really quite simple.
Hashnode·4yLocal Storage and Session Storage (JavaScript)
Local storage and session storage store key-value pairs. Local storage stores an array as a string, while session storage stores a pair. To get an array from local storage, we use JSON.parse. In order to remove a particular key- value pair, we can use localStorage.remove.

Medium·4yScopes In Javascript.
In Javascript, we have 3 types of scope: block scope, function scope and global scope. Scope defines the accessibility(visibility) of the variable, which means whether the variable is accessible or not. Before ES6 (2015), JavaScript had only Global Scope and Function Scope. I hope it helps you to understand scope in a better way.
inDepth.dev·4y101 Javascript Critical Rendering Path
Every webpage has a Document Object Model or a DOM. This is an object-based representation of the entire HTML page, which is in the parsed state. Once the HTML is parsed, a DOM tree is built. The DOM Tree contains objects. The CSS Object Model takes care of the styles present in association with the DOM tree.
