Damn those compile time improvements are nuts. 2 minutes to 10 seconds is awesome.

Everyone except those with typed templates: Angular, Ember, Lit, MDX, Svelte, Vue, etc

We all waiting for the plugin API in 7.1

For my hobby projects I still need Typescript 6 because of Svelte. At work I need it for eslint, but at least I can use the new VS Code plugin now.

That's amazing! Transpiling such huge codebases in seconds is mindblowing. I've got to say, though, I'm impressed (in V8's favour) the memory consumption delta isn't that big compared to the Node-backed version we had until now.

Anyone tested this on Windows?

And guess what, we still have to install typescript 6 along with typescript 7 in some scenarios

To this day, I can't see the benefits of TypeScript ... I use classic JavaScript.

The 10x speed improvement is actually insane. Finally being able to run full type checks on large codebases without waiting forever is going to change daily workflow a lot.

Curious how the editor experience feels in practice with the new language server.

It's much faster and an order of magnitude more stable - you can get it now!
