Output array without numeric index

Question

The following code:

    for(i=0; i<3; i++){
         a = {};
         a['name' + i] = i;
        data.push(a);
}

...outputs the following array:

{
1:{name0:0},
2:{name1:1},
3:{name2:2}
}

How can I amend the code so that it outputs the array as follows:

{
name0:0,
name1:1,
name2:2
}

The reason I need to do this, is that I'd like to be able to reference my array later on like so: data[name1], instead of having to loop through the entire array to look for the value that I need.

Use a plain object instead of an array data = {} and then use data['name' + i] = i in the loop. You don't need a. — nnnnnn

well you should use data directly as an object, rather than having it as an array (and thus having it as an array of objects)

 for(i=0; i<3; i++){
    data['name' + i] = i;
}

Keep in mind that data should be an object (initialized as var data = {})

This is the correct answer. My mistake was trying to push the values into the array each time. I will accept this answer as correct.

Do you need to initialize data ... var data = {};? OP has not shown how data is initialized but from the operations it's var data = [];.
