Community Picks·4yJavaScript Visualized: the JavaScript Engine
JavaScript is based on the V8 engine used by Node.js and Chromium-based browsers. The engine tries to avoid parsing code that's not necessary right away. The optimized machine code can simply be re-used in order to speed things up. V8 is open source and has some great documentation on how it works under the hood.

Medium·3ySay bye bye to bad javascript practices
Some small practices in programming can have a continuously negative impact on the code we write and the product we create as the end result. It’s important to share what they are and why you should avoid them at all costs. Here are a few tips and reminders to help you write code comments like a pro.
Community Picks·4yJavaScript Patterns Workshop
The goal is to raise awareness to certain patterns, the problems they solve, and their implementation. The patterns covered on this website and in the workshop can guide you when facing a problem other developers have encountered many times before, but are not a blunt tool for jamming into every scenario.
Changelog·4yBun is a fast all-in-one JavaScript runtime
Bun is a modern JavaScript runtime like Node or Deno. It was built from scratch to focus on three main things:Start fast (it has the edge in mind) New levels of performance (extending JavaScriptCore, the engine) Being a great and complete tool (bundler, transpiler, package manager)
CSS-Tricks·4yThe 60 Hottest Front-end Tools of 2021 | CSS-Tricks
The Web Tools Weekly newsletter archives have been compiled into a list of the 60 most popular front-end tools of the past year. I’m sure there are at least one or two listed here that you can start using in your projects today. Some of these tools are super-practical, while others probably only made this list due to curiosity.
DEV·4yAn animated guide for Node.js event loop
Node.js is single-threaded, but what does it mean in practical terms? We will explore it by following this piece of code step by step. The V8 JavaScript engine manages a call stack, an essential piece that tracks which part of our program is running. The event loop connects the queue with the call stack.

Hashnode·4yJokes only programmers will understand
To understand these jokes, you have to be a programmer, and if you're not don't worry. Laugh and also share them with your friends that are programmers. It isn't an easy thing to become a programmer. You need some minutes to at least laugh and forget the stress you've been through.
Hacker News·4yRun Python in your HTML
PyScript is a framework that allows users to create rich Python applications in the browser using HTML’s interface. It aims to give users a first-class programming language that has consistent styling rules, is more expressive, and is easier to learn. PyScript is just HTML, only a bit (okay, maybe a lot) more powerful, thanks to the rich and accessible ecosystem of Python libraries.

Harvard CS50 is one of the most popular beginner computer science courses in the world. The course teaches students how to think algorithmically and solve problems efficiently. Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web programming.
freeCodeCamp·4yHow to Prepare for React Interviews – Front-End Technical Interview Guide
A polyfill is a custom implementation of native JavaScript functions. The.map() polyfill method takes in a callback that gets executed inside the myMap body. This is nothing but the length of the array through which theMyMap function is called. Since map() returns a new array, we create an empty array and push the results into it. In order to implement debouncing, let's take an example.
Community Picks·3yReact - Best Practices
In JavaScript, you can adopt ES6 syntax to make your code cleaner. Don't Forget key Prop With map in JSX Always assign a unique value to the prop to every JSX element while mapping from an array. Use Ternary Operator instead of if/else if Statements makes your code bulky.

Community Picks·4yJavaScript from ES6 to ES12 in 2022
JavaScript from ES6 to ES12 in 2022 is one of the three most crucial programming at front-end positions. There are some new scripts to support software engineers by ES6 ~ ES12 for now. ECMA specification is made up of parties, including browser vendors, who meet to push JavaScript proposals. The promise is a solution to asynchronous (non-synchronous) writing, which is more elegant than the original callback writing. In the early days, it was a suite of the open-source community.

Speech recognition API was added to the specs and we got partial support on Chrome, Safari, Baidu, Android webview, iOS safari, samsung internet and Kaios browsers (see browser support in detail) The implementation I made currently supports English and Spanish just to showcase.
Medium·4yLodash is dead. Long live Radash.
Lodash was created in 2009 (as Underscore) and rose to power after a fork (as Lodash) around 2012-2013. The language was too unsafe, unmaintainable, and unwieldy. The addition of optional chaining and null coalescing alone makes a large handful of Lodash functions obsolete. The source code is maintained with understandability for newcomers as a top priority.
Hashnode·4yJavaScript object destructuring tips
Destructuring is an extremely useful way of extracting properties from objects. Destructuring also works on arrays, but let's focus on objects for this one. We can omit the double use binding of the name properties and destructure the properties like this. With destructuring, we can also target nested properties.
