description: Throws a TypeError on a non-callable [Symbol.iterator] (object) (Static async generator method as a ClassExpression element)

flags: [generated, async]

ClassElement :

1. Let exprRef be the result of evaluating AssignmentExpression.
|
|
2. Let value be ? GetValue(exprRef).
|
|
3. Let generatorKind be ! GetGeneratorKind().
|
|
4. Let iterator be ? GetIterator(value, generatorKind).
|

...
|
|
|
|
GetIterator ( obj [ , hint ] )
|
|
|
|
...
|
|
3. If hint is async,
|
|
a. Set method to ? GetMethod(obj, @@asyncIterator).
|
|
b. If method is undefined,
|
|
i. Let syncMethod be ? GetMethod(obj, @@iterator).
|
|
...
|
|
|
|
GetMethod ( V, P )
|
|
|
|
...
|
|
2. Let func be ? GetV(V, P).
|
|
...
|
|
4. If IsCallable(func) is false, throw a TypeError exception.
