| description: Return undefined regardless the result of CleanupFinalizationGroup |
| info: | |
| FinalizationGroup.prototype.cleanupSome ( [ callback ] ) |
| |
| 1. Let finalizationGroup be the this value. |
| 2. If Type(finalizationGroup) is not Object, throw a TypeError exception. |
| 3. If finalizationGroup does not have a [[Cells]] internal slot, throw a TypeError exception. |
| 4. If callback is not undefined and IsCallable(callback) is false, throw a TypeError exception. |
| 5. Perform ? CleanupFinalizationGroup(finalizationGroup, callback). |
| 6. Return undefined. |
