passing a string to a function to get used as an object in javascript/jquery

Question

I have a loop that calls a JSON array as an object. I want to itterate through the array to find items called match, the match names are called - match1, match2 etc.

It works instead of using the created var finalM i type match1, match2 etc.

    var theObject = data; // get json data 
    var i;
      for (i = 0; i < theObject.length; i++){
          var add = i + 1 ;
          var finalM = "match"+ add; 
          $('.someDiv').append(
              theObject[i].finalM.someVal
          );
    }

I know its something to do with the scope of the string, but can't find a good example to help me with the problem.

@T.J.Crowder yes that would be good. i was basically asking for a demo thats it. be it a fiddle or stack snippet. — Manish, Aug 17 '16 at 05:48
It's kind of funny since you already know how to use a variable to access a property: `theObject[i]`. — Felix Kling, Aug 17 '16 at 05:50
@Manish will make one for next time, i just didn't understand the syntax of the string to object in a looped array, smarx was right. will be answering correct shortly — Paddy, Aug 17 '16 at 05:51

I think you want this:

$('.someDiv').append(
    theObject[i][finalM].someVal
);
