TypeScript

JavaScriptLanguageTypechecker

TypeScript is a programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript and adds optional static typing to the language. TypeScript is designed for the development of large applications and transcompiles to JavaScript. As TypeScript is a superset of JavaScript, existing JavaScript programs are also valid TypeScript programs.

Hey @typescript necromancers, I'm hitting a wall again. How should I pass the generic return type of an optional function argument that has a default value? https://t.co/6dr5juGFNu

Looking to integrate @typescript in a monorepo? Are you overloaded, confused? I've been there... As such, I've conjured all my experience and knowledge on this subject to provide an in-depth guide for using TS project references. I hope it helps! https://t.co/kRYBf7veU3

Many think that anything written in @typescript is 100% "type-safe", but that's not the case. This usually boils down to the decision between using "any" or generics. It's easy to choose "any" when the latter also means learning a magnitude of complexity on behalf of your users.

One of the areas that @typescript can get a little brittle 馃槒 is when you start going across file-boundaries. Where you'd normally infer a type from scope, you need to export+import/declare compatibility. Depending on structure, you might find yourself in a circular dependency...

TypeScript has become the slowest part of my dev stack. It鈥檚 an obvious laggard. I agree that the @typescript team needs to move the compiler to Rust, Go, or something faster than JS. It鈥檚 the single greatest risk to TS鈥 future. https://t.co/wur54rdkMW

Current status: time-travel debugging @typescript's node run in a browser. @replayio is a hero tool I don't deserve. My dev life consists of 2 major eras now - I call them pre-Replay and post-Replay

I'm going to be speaking at @githubuniverse 2021 on the @TypeScript team's automation behind @DefinitelyTyped (one of the fastest moving repos on @GitHub) What parts are folks interested in me diving into?

Shipped my @typescript PR which lets you override the library files which ship in @TypeScript with your own versions, so for 4.5 you鈥檒l be able to safely lock your DOM types (via types/web) - or use stricter versions of the libs in the future. https://t.co/IMzM2skuQi https://t.co/tgWO2e2Uc7

Shipped in @TypeScript 4.5 - if you accidentally put compiler options in the root of the tsconfig.json (instead of inside a 鈥渃ompilerOptions鈥 obj) then TypeScript will raise an error. https://t.co/2hv6Skk4Lp
