  • Pluggable and configurable to your team's own rules.¹
  • Finds and auto-fixes reported code problems.¹
  • De facto standard across JS tutorials and production stacks.³
  • Works across stacks: React Native, Node, AWS CDK setups.⁴

Cons

  • JavaScript-only — useless for other languages.¹
  • No vendor support, demo, or case studies; pure community project.⁷
  • Usually needs pairing with Prettier — more tooling to maintain.⁵

Gotchas

  • mediumFree, but real cost is engineer time: config, plugins, and major-version upgrade migrations.⁴
