shorif

The [a+name] is not allowed!! – Hangover Sound Sound Feb 03 '22 at 16:36
@HangoverSoundSound, sure it is. Did you try? – trincot Feb 03 '22 at 16:39
Use the same syntax as you did to define the property: `return this[a+name]` – trincot Feb 03 '22 at 16:39
Very strange that this question was closed. Shorif, remove ``this.`` from ``this.a`` so its just ``a``, and you should not have any more problems. – Kenny.Harrer Feb 03 '22 at 16:39
@Kenny.Harrer, it is not strange that it was closed, since this has been asked many times before in different ways. And what you propose will just print the value of `a`, not the property in the object, which is what the Asker wants. – trincot Feb 03 '22 at 16:40
@Kenny.Harrer, I provided help above. Did you read my comment? And yes, this is duplicate. But still I provided the way out in comments. How is that not helping? – trincot Feb 03 '22 at 16:42
@trincot When I wrote my comment you had not commented yet. It's a misunderstanding. – Kenny.Harrer Feb 03 '22 at 16:45
