SuperCall may may only occur in eval code for direct eval within a
|
|
constructor method
|
|
info: |
|
|
[...]
|
|
4. Let inMethod be false.
|
|
5. Let inConstructor be false.
|
|
6. If thisEnvRec has a [[HomeObject]] field, then
|
|
a. Let inMethod be true.
|
|
b. If thisEnvRec.[[FunctionObject]] has a [[Construct]] field, let
|
|
inConstructor be true.
|
|
7. Let script be the ECMAScript code that is the result of parsing x,
|
|
interpreted as UTF-16 encoded Unicode text as described in 6.1.4, for the
|
|
goal symbol Script. If inMethod is false, additional early error rules
|
|
from 18.2.1.1.1 are applied. If inConstructor is false, additional early
|
|
error rules from 18.2.1.1.2 are applied. If the parse fails, throw a
|
|
SyntaxError exception. If any early errors are detected, throw a
|
|
SyntaxError or a ReferenceError exception, depending on the type of the
|
|
error (but see also clause 16). Parsing and early error detection may be
|
|
interweaved in an implementation dependent manner.
