tsconfig allowJS & eslint all js check

[manudeli]

          I respect your opinion, and I believe that excluding checks for .js files in ESLint settings might be a somewhat regrettable choice. ESLint provides various rules that help maintain code conventions, and these rules still hold significant meaning for files that do not use TypeScript. For example, rules like import/order and prettier can greatly enhance code readability and maintain consistency within the project. From this perspective, I think it is more desirable to apply ESLint checks to all files.

@SEOKKAMONI In my opinion, this is not something we must do right now, so I'll close it for now. Feel free to reopen if you think otherwise.
