Javascript expression to define object’s property name?

I’m trying to add objects to an array, but I want to have the name and value to be dynamic. Here’s an example:

    (function(){
        var data = [];

        for(i=0; i<5; i++){
            data.push({'name' + i: i});
    }

        console.log(data);
    })()

I guess I can’t use a variable for the property so I’m not sure what to do.

If you want to use a dynamically named property, you need to use array access notation:

var temp = {};
temp['name' + i] = i;
data.push(temp);

_{In the IIFE:}

(function(){
    var data,
        temp,
        i;
    data = [];
    for (i = 0; i < 5; i += 1) {
        temp = {};
        temp['name' + i] = i;
        data.push(temp);
    }
    console.log(data);
}());
