Can we plz add eslint to the project at some point thx

also this should include running the linter and adding the linter to whatever CI we have set up

I like the eslint recommended set of rules, which roughly are the de facto standards. I'd suggest:

module.exports = {
  env: {
    node: true,
    browser: true,
  },
  extends: 'eslint:recommended',
  parserOptions: {
    sourceType: 'script',
    ecmaVersion: 10,
  },
  rules: {
    'no-console': 0, // I'd leave this in til we get a proper logging library
  },
}

I ran eslint . with that config and we have: 14 errors, 29 warnings. Most warnings are about console logs and the errors don't look too complicated.
