Pros
  • AST-based transforms support structural, large-scale code changes
  • Parser options include Babel, Flow, TypeScript, and TSX
  • Dry runs, parallel workers, and testing utilities support safer refactors
  • Semantic patches express structural matches and transformations
  • Applies changes across directories, files, and multiple code sites
  • Free, open-source workflow with diff and in-place transformation modes
Cons
  • Scope is limited to JavaScript, TypeScript, and Flow
