Hi @tqchen . Thank you for reviewing my PR. As I am reading the code on web, I found the typescript and eslint configuration can be significantly improved.
I assume the liner and type checker under web directory is not working for other developers as well, because some of non-recommended code style shows up. like ==. It is best to use === in JavaScript. Those code can run, but the best paractice is to avoid them.

I will submit a PR #15452 fix the eslint and typescript config and fixes suggested by them to improve the DX and reliability of the current code.

Would you mind reviewing it then? Thanks in advance.
