esid: sec-finalization-registry.prototype.cleanupSome
description: Return undefined regardless the result of CleanupFinalizationRegistry
info: |
FinalizationRegistry.prototype.cleanupSome ( [ callback ] )
1. Let finalizationRegistry be the this value.
2. If Type(finalizationRegistry) is not Object, throw a TypeError exception.
3. If finalizationRegistry 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 ? CleanupFinalizationRegistry(finalizationRegistry, callback).
6. Return undefined.
