Today we’re excited to announce the release of TypeScript 4.8! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. These types let you put your expectations and assumptions into your code, and those assumptions can then be checked by the TypeScript type-checker. This checking can help avoid typos, calling uninitialized values, mixing up
All JavaScript and TypeScript Features of the last 3 years
TypeScript as envisioned by Stable DiffusionThis article goes through almost all of the changes of the last 3 years (and some from earlier) in JavaScript / ECMAScript and TypeScript . Not all of the following features will be relevant to you or even practical, but they should instead serve to show what’s possible and to deepen your understanding of these languages. There are a lot of TypeScript fe
When a single-page application needs to fetch data from a remote source, it needs to do so while remaining responsive and providing feedback to the user during an often slow query. Five patterns help with this. Asynchronous State Handler wraps these queries with meta-queries for the state of the query. Parallel Data Fetching minimizes wait time. Fallback Markup specifies fallback displays in marku
The proposal “Pipe operator (|>) for JavaScript” (by J. S. Choi, James DiGioia, Ron Buckton and Tab Atkins) introduces a new operator. This operator is an idea borrowed from functional programming that makes applying functions more convenient in many cases.

Today we’re excited to announce our Release Candidate (RC) of TypeScript 4.8. Between now and the stable release of TypeScript 4.8, we expect no further changes apart from critical bug fixes. To get started using the RC, you can get it through NuGet, or use npm with the following command: npm install -D typescript@rc You can also get editor support by Downloading for Visual Studio 2022/2019 Follow
A few months ago we saw a post on the r/programminghorror subreddit: A developer describes the struggle of identifying a syntax error resulting from an invisible Unicode character hidden in JavaScript source code. This post inspired an idea: What if a backdoor literally cannot be seen and thus evades detection even from thorough code reviews? Just as we were finishing up this blog post, a team at

Composables are, by far, the best way to organize business logic in your Vue 3 app. They let you extract small pieces of logic into functions that you can easily reuse repeatedly. This makes your code easier to write and read. Since this way of writing Vue code is relatively new, you might be wondering what the best practices are when writing composables. This tutorial series will serve as your gu
