Create dynamic name for value in Array

Question

How I can create dynamic name of object from my value in array? For example:

This is my code:

var data=[{"column":"1", "count":"1"},{"column":"2", "count":"2"},{"column":"3", "count":"3"}];
var data2=[{"column":"1", "count":"5"},{"column":"2", "count":"2"},{"column":"3", "count":"7"}];
var data3=[{"column":"1", "count":"9"},{"column":"2", "count":"6"},{"column":"3", "count":"1"}];
var obj=[];
for (i=0;i<data.length;++i)
 obj.push({date: data[i].column, count1: data[i].count});
for (i=0;i<data2.length;++i)
 obj[i].count2 = data[2].count;
for (i=0;i<data3.length;++i)
 obj[i].count3 = data3[i].count;
console.log(obj);

and this is link for jsfiddle: https://jsfiddle.net/r4tnewxg/

As you can see in the example is part of "count 1", etc. You can do it in a dynamic way? For example, the for loop and taking advantage of the 'i'? Then the name would be a "count" + i " results: " count1 "," count2 " etc.

Answer 1

If I understand you correctly, you are after something like this maybe?

var obj = {};
...
obj["count"+i] = ...

• radek.: "obj[i].count+i" This is the problem. I can't write 'count+i' for new element from my array
• bgse: Yes, you'd have to use an object actually.

Answer 2

You Simply use concat Function

var obj=data.concat(data2,data3);
