• 8264d19: Initial release

  deadCodeElimination

  Eliminates unused code from the Babel AST by repeatedly removing unreferenced identifiers.

  deadCodeElimination(ast)

  findReferencedIdentifiers

  Find identifiers that are currently referenced in the Babel AST.

  Useful for limiting deadCodeElimination to only eliminate newly unreferenced identifiers,
  as a best effort to preserve any intentional side-effects in the source.

  let ast = parse(source, { sourceType: "module" })
  let referenced = findReferencedIdentifiers(ast)
  
  traverse(ast, {
    /* ... your custom transform goes here ... */
  })
  
  deadCodeElimination(ast, referenced)
