React is poorly supported (especially .js file)

[rui-ktei]

Created a test.js and wrote very simple React code. This is what I got:

To be honest, currently VS Code has very bad support of React syntax and it's basically useless. This issue has been there for quite some time... just wondering: is it going to be fixed?

You're probably missing Props & State interface types.

interface Props { /*...*/ }
interface State { /*...*/ }
class MyComponent extends React.Component<Props, State> {
  // ...
}

See its declarations file.

@louy I wasn't using typescript. I just wrote some ES6 + React.

@rui-infotrack oh sorry. Ignore what I said then. Someone else was having the same problem with tsx and I must've overlooked your issue.
