| info: | |
| MethodDefinition : set ClassElementName ( PropertySetParameterList ) { FunctionBody } |
| 1. Let key be the result of evaluating ClassElementName. |
| 2. ReturnIfAbrupt(key). |
| 3. If the function code for this MethodDefinition is strict mode code, let strict be true. Otherwise let strict be false. |
| 4. Let scope be the running execution context's LexicalEnvironment. |
| 5. Let closure be FunctionCreate(Method, PropertySetParameterList, FunctionBody, scope, strict). |
| 6. Perform MakeMethod(closure, homeObject). |
| 7. Perform SetFunctionName(closure, key, "set"). |
| 8. If key is a Private Name, |
| a. If key has a [[Kind]] field, |
| i. Assert: key.[[Kind]] is "accessor". |
| ii. Assert: key.[[Brand]] is homeObject. |
| iii. Assert: key does not have a [[Set]] field. |
| iv. Set key.[[Set]] to closure. |
| b. Otherwise, |
| i. Set key.[[Kind]] to "accessor". |
| ii. Set key.[[Brand]] to homeObject. |
| iii. Set key.[[Set]] to closure. |
| 9. Else, |
| a. Let desc be the PropertyDescriptor{[[Set]]: closure, [[Enumerable]]: enumerable, [[Configurable]]: true}. |
| b. Perform ? DefinePropertyOrThrow(homeObject, key, desc). |
