I am using an object in javascript and I need to get it's values by dynamic attributes, how do I use concatenation to get the right syntax ?

To make it clearer this is my code:

dataObj[0].xxxxxxxx.Value;(xxxxxxx -> dynamic)

I tried: set my attr name in a var :

var curr = "games" - > `dataObj[0].+curr+.Value;`    //- NO GOOD
use [] - > `dataObj[0].[curr].Value`                 //- NO GOOD
use +"+ - > `dataObj[0].+'"'+curr+'"'+.Value`        //- NO GOOD

Use second pair of [] without the dot: `dataObj[0][curr].Value` – Krypt1 May 29 '18 at 11:15

@Quentin Why not ?! :- O – Damkulul May 29 '18 at 11:22
@Damkulul — Because there is no good approach to solving your problem that involves concatenation. – Quentin May 29 '18 at 11:24
