Summary

All of the js sub-repos in the monorepo have their own lint settings. For eslint before 9, this was best practice. It is difficult to find a "one size fits all" lint approach for JS, since nodejs has different rules from vanilla js, react has its own special rules, the browser has different globals vs node, different test engines also have different globals, different standards have different syntax, some repos have a good reason to use multiple standards, etc.

We want all js to be linted. And we want there to be a maintainable and as-standardized-as-possible approach.

With eslint 9, the "flat config" is introduced which allows a single config file to handle various rulesets across a monorepo. We implement this approach here, deleting all legacy lint settings (many of which were never implemented in arc lint).

We correct all lint issues discovered by this implementation now that arc lint is picking everything up.

Test Plan

CI for all lint changes, arc lint --everything
