JSX extensions in create-react-app

[shreyasvimal]

I recently created a new React app with create-react-app and noticed that there is no JSX extensions. I would like to know the reason why JSX was replaces with JS extensions.

Thanks.

@shreyasvimal I'm not sure what you mean CRA has used JS extensions since the beginning
https://github.com/facebook/create-react-app/tree/2305bf23976cb8adf18c4583050fc50fb92d67ce/src

The two extensions are interchangeable in CRA, and tend to be interchangeable in general https://stackoverflow.com/a/46169636

You can use jsx extensions if you want.
