Surely the huge win for JSX is that you can type check it?

I have a Typescript + Angular 1 project. The app logic feels robust as Typescript makes sure I'm using the right identifiers, variables aren't null/undefined etc. The Angular templates are a constant source of annoyance: they aren't type checked and aren't part of automatic variable renaming refactorings.

This is ultimately what makes React the right choice for me. A big part of the whole code=data thing is that code can be typed, which means now your data (markup) can be typed as well.

Of course this only really matters if you use Typescript/Flow.

Wow that is a good point! I have the same experience with Angular.js 1 and TypeScript.

Can someone confirm that you cannot type check Vue.js templates (without using Vue.js JSX support of course)?

I'm not a Vue user but I can't see how they would be type checkable without using JSX.

For the Angular 1 project, I'm thinking as a stepping stone we could introduce JSX templates before migrating to Vue or React later.
