How to assign a value of variable as name of an object in javascript

Question

I pass a string through "objName".

I want this to to be stored in the line: facebookData.objName

For example:

if I invoke the function like, fetchData(0, response, "friendsCount"), the object should be like: facebookData.friendsCount = dLen;

Note: facebookData is a global object.

             function fetchData(dLen, response, objName){

                if(response.paging){

                    if(!response.paging.next){

                        facebookData.objName = dLen; //Problem is here
                        return dLen;
                    }
                    else{
                        -------------------
                       fetchData(dLen, response, objName);
                    }
                }

You should use bracket notation: facebookData[objName] = dLen; — go-oleg

Use brackets:

facebookData[objName] = dLen;
