Question

I want to do the following:

// an object
var object = {
    one: null,
    two: null,
    three: null
};

// an array
var array = ['this is one', 'this is two', 'this is three'];

I now want to merge them both together so I get;

var merged = {
    one: 'this is one',
    two: 'this is two',
    three: 'this is three'
};

I don’t want to use any 3rd library just pure javascript (ECMA5).

So what is the trick?

Try this:

// an object 
var object = {
    one: null,
    two: null,
    three: null
};

// an array 
var array = ['this is one', 'this is two', 'this is three'];

function merge(arraysrc, array2dest) {

    var x, i = 0;

    var merged = [];

    for (x in array2dest) {
        var obj = {};
        obj[x] = arraysrc[i++];
        merged.push(obj);
    }
    return merged;
}

var a = merge(array, object);

alert(JSON.stringify(a));​
