emmet support within JSX

@iwaldman can you elaborate?

[DanielRosenwasser]

Emmet (see #4835 (comment) and #6508 (comment)), is a macro system for HTML-like languages that works as you type. VS Code has support for it as far as I know (microsoft/vscode#732).

I understand, i was more interested in what the request was, is it to develop an emmet like system for TS? just JSX? why not just use emmet?

In TypeScript we do have namespaces. In JavaScript there are idioms for this. I sometimes write something like this:

// Create a namespace "memDb.controllers"
window.memDb = window.memDb || {};
memDb.controllers = memDb.controllers || {};

memDb.controllers.AClass = class { 
 // ...
};

Should something like this be supported by Salsa? How to do namespaces in Salsa?

@aersamkull this is tracked by #7632

[chicoxyzzy]

Are language extensions (analogues to babel plugins) planned in Salsa? It'll be cool if we'll be able to throw out Babel which is used mainly for React optimisations (1, 2) (BTW these two might be in core of TS) and code instrumentation.

Salsa could be used to generate definition files from js, like Typescirpt does from ts. There are any plans for this?

[aluanhaddad]

@AbraaoAlves #7546 tracks that. It would be super useful.

Would be great to have AMD module support! 👍 :)
