I know, and that’s a definite plus. I don’t have to worry that it will go away or lose all the main contributors.

But is not developed by the same developers/company as React.

I will say given what TS is competing against the fact that it so well used is rather compelling. I know all of Angular is also written in TS. It’s clearly very heavily used.

React can fade but JavaScript won't..(it could only evolve). outside react Typescript is the clear winner and even most of the react projects I am seeing is using Typescript. I would say Typescript is the clear winner. Also VSCode is now far popular than other editors which is developed by Microsoft as well..

Also typescript and React go really really well because typescript can do tsx which is a strongly typed flavor of jsx.

Being able to use good code completion when using other people’s components is a huge boon.

Isn't React in itself a view library? What's there to develop on it?

I'm really interested in this, as I'm a happy Angular user. (I'm primarily a non-frontend dev/tech/ops, but I occasionally I do frontend development.) So every time I look at a React component/codebase I'm completely lost, and I'd like to understand why and what and how.)
