How can I use dynamic value in map function in javascript?

Question

Hi is there any way to use a dynamic value in .map() of javascript function which is coming from outside?

Example:

data.map(item=> item."dynamic");

How to do this? or is it possible at all? I want to do this because, I want to use this map not for a single value like item.name but dynamically.

Try with square ([]) bracket that allows dynamic property:

data.map(item=> item[dynamic])

Yes that helps me but, if i want to go a little bit deeper than its not actually working. i mean if i pass something like "details.photo" its not working :/ – Ozzie Apr 07 '20 at 13:45
@Ozzie, I believe there is no built-in way to achieve that:) – Mamun Apr 07 '20 at 13:52
so if i pass a value like "data.user" will it work? to access in a object in the item? – Ozzie Apr 07 '20 at 14:21
@Ozzie, no, that will not work......... – Mamun Apr 08 '20 at 02:03
