ECMAScript function objects defined using syntactic constructors in strict mode code must
|
|
not be created with own properties named "caller" or "arguments". Such own properties also
|
|
must not be created for function objects defined using an ArrowFunction, MethodDefinition,
|
|
GeneratorDeclaration, GeneratorExpression, AsyncGeneratorDeclaration, AsyncGeneratorExpression,
|
|
ClassDeclaration, ClassExpression, AsyncFunctionDeclaration, AsyncFunctionExpression, or
|
|
AsyncArrowFunction regardless of whether the definition is contained in strict mode code.
|
|
Built-in functions, strict functions created using the Function constructor, generator functions
|
|
created using the Generator constructor, async functions created using the AsyncFunction
|
|
constructor, and functions created using the bind method also must not be created with such own
|
|
properties.
