Today we’re excited to announce the release of TypeScript 5.5! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s editor tooling like the auto-completion, code navigation, and refactorings that you might see in editors like Visual Studio and VS Code. In fact, if you write JavaScript in either of those editors, that ..read more

Today we’re excited to announce the release of TypeScript 5.3! If you’re not familiar with TypeScript, it’s a language that adds type syntax to JavaScript to bring type-checking. Type-checking can catch all sorts of issues like typos and forgetting to check for null and undefined. But types go beyond type-checking – the same analyses of TypeScript’s type-checker are used for rich editor tooling like auto-completion, code navigation, and refactorings. In fact, if you’ve been writing JavaScript in editors like Visual Studio or VS Code, that experience is powered by TypeScript! To get started usi ..read more
