[MikeMcC399]

Change

• Add ESLint modules
  • @stylistic/eslint-plugin@4.2.0
  • eslint@9.22.0
  • eslint-plugin-cypress@4.2.0
  • globals@16.0.0
• Add script lint to package.json
• Add job lint to circle.yml
• Lint and correct all JavaScript files
• Exclude *.js files from formating with Prettier to avoid overlap with @stylistic/eslint-plugin

Verify

Execute

npm ci
npm run lint

and confirm no errors are reported and no suggestions for change are made.

I'm happy you agree 🙂 ! There are a couple more PRs to do for Prettier, then the linting is set up for this repo. That should make it cleaner going forward.
