description: An ArrowFunction in global code may not contain SuperProperty
|
|
info: |
|
|
- It is a Syntax Error if StatementList Contains super unless the source code
|
|
containing super is eval code that is being processed by a direct eval that
|
|
is contained in function code that is not the function code of an
|
|
ArrowFunction.
|
|
|
|
14.2.3 Static Semantics: Contains
|
|
|
|
With parameter symbol.
|
|
|
|
ArrowFunction : ArrowParameters => ConciseBody
|
|
|
|
1. If symbol is not one of NewTarget, SuperProperty, SuperCall, super or
|
|
this, return false.
|
|
2. If ArrowParameters Contains symbol is true, return true.
|
|
3. Return ConciseBody Contains symbol.
|
|
|
|
NOTE Normally, Contains does not look inside most function forms. However,
|
|
Contains is used to detect new.target, this, and super usage within an
|
|
ArrowFunction.
