Häufige Annahme

transformFromAstSync modifies the provided AST object in place during traversal and populates result.ast with the transformed tree.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• transformFromAstSync preserves the input AST node unmodified and sets result.ast to null unless cloneInputAst is set to false and ast is set to true.
• inputAst.program.body[0].kind remains 'let' when cloneInputAst defaults to true
• defaultResult.ast is strictly null on default invocations
• cloneInputAst: false mutates the passed AST in place, changing kind to 'const'
• explicitResult.ast returns the root File AST node only when options.ast is explicitly true
