Great idea!

I am OK with doing it in this PR.

N00b question: Is there a possibility to fail the build when files are not properly formatted?

Perfect. I'll push the formatting updates to this PR in the morning.

N00b question: Is there a possibility to fail the build when files are not properly formatted?

Absolutely. I'll add a GitHub Action workflow to validate the formatting. Linting will need to come much later if/when the hundreds of errors are resolved.

@nscuro @msymons - I have added a GitHub workflow, which for now i've set to continue-on-error.

Some stats before running the automated linting fixes

ES-Lint: 15380 problems (15380 errors, 0 warnings)
Prettier: Code style issues in 175 files

After running prettier for code formatting

640 problems (640 errors, 0 warnings)
