Turbo 8 is dropping TypeScript
By all accounts, TypeScript has been a big success for Microsoft. I've seen loads of people sparkle with joy from dousing JavaScript with explicit types that can be checked by a compiler. But I've never been a fan. Not after giving it five minutes, not after giving it five years. So it's with great pleasure that I can announce we're dropping TypeScript from the next big release of Turbo 8. The fac

Most users of Volar know it as the official Vue.js VSCode extension. It started as a personal project when the official recommendation was still Vetur, and over time got adopted as the new official extension due to improved architecture and performance. As a project created to improve the quality of life for developers, we spent over two years before reaching 1.0, and have been continuously shippi
Typescript is terrible for library developers
I love typescript as an end-developer. I feel like it dramatically reduces the need to manually write automated tests. It cannot be overstated how much work is involved with writing and maintaining good automated tests so anything that can reduce its utility is a huge boon to productivity. However, as a library developer, I hate typescript. There are a lot of reasons why typescript sucks for libra
Announcing TypeScript 4.8 - TypeScript
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
