ECMAScript 5 introduced new Object methods to Javascript. Among them preventExtensions, seal, freeze methods will be compared to each other.
A little guide on how you can improve your applications performance using JS concurrency model and leveraging code parallelism.
In this blog post, we take a closer look at how the ECMAScript specification sees JavaScript objects. In particular, properties are not atomic in the spec, but composed of multiple attributes (think fields in a record). Even the value of a data property is stored in an attribute!
Web Sockets allow real-time communication between the client browser and a server. They are different from HTTP because they not only allow client to request data from the server but also allow server to push data from the server.
Are you looking for an opportunity to start with TypeScript? I've started a new video course to help you with that. We'll walk through some very basics of types to advance topics. We'll see how to migrate an existing project to TypeScript, and finally, learn to configure Visual Code and Vim for a comfortable and productive workflow. While it is still in progress, you can order it now with 67% discount using this link.
We’re thrilled to announce the release of TypeScript 3.7, a release packed with awesome new language, compiler, and tooling features. If you haven’t yet heard of TypeScript, it’s a language based on JavaScript that adds static type-checking along with type syntax.
Curious about all the TypeScript 3.7 hype? Check out this video to learn more about optional chaining and nullish coalescing in TypeScript 3.7.
TypeScript has a lot of advantages. However, it’s not often that you are starting a brand new project. More often though you are working on an existing codebase and simply don’t have luxury of rewriting everything from scratch. After all, we need to deliver new features and fix annoying bugs.
Destructuring assignment and rest parameters are awesome and typical in codebases these days. Is it possible to strongly-type these though
At React Conf 2019 we announced an experimental release of React that supports Concurrent Mode and Suspense. In this post we’ll introduce best practices for using them that we’ve identified through the process of building the new facebook.com.
I've been playing around with React’s new Concurrent Mode and it is amazing. A little mind-bendy, a dash mad, and a whole lot of wonderful.

Hi, this is part 6, where I am adding responsiveness with ResizeObserver and a custom hook!
The situations where memory leaks are most likely to happen, and how you can deal with them using Chrome DevTools.
Algebraic Structures are something I wish I’d understood better, sooner. I had a hazy idea of what they were, but didn’t know the correct terminology. That was a massive barrier to finding out more. This article is my attempt to stop that happening to others. We'll look at: What are algebraic structures? How do we use them in JavaScript? Why would we bother? What's the big deal?
Open Collective previously promoted the use of postinstall messages, output in the developer terminal each time someone installed a package. This practice proved controversial, and in September we stopped encouraging it
