description: Throws a TypeError on a non-callable [Symbol.iterator] (symbol) (Async Generator method as a ClassDeclaration element)
esid: prod-AsyncGeneratorMethod
features: [Symbol.iterator, Symbol.asyncIterator, async-iteration]
flags: [generated, async]
info: |
ClassElement :
MethodDefinition
MethodDefinition :
AsyncGeneratorMethod
Async Generator Function Definitions
AsyncGeneratorMethod :
async [no LineTerminator here] * PropertyName ( UniqueFormalParameters ) { AsyncGeneratorBody }
YieldExpression: yield * AssignmentExpression
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.
