Answer 1

To the first part of your question:

You could use Array#forEach() and assign all properties with the correspondet value.

var key = ['id', 'name', 'address'],
    value = [7, 'John', 'New York'],
    object = {};

key.forEach(function (k, i) {
    object[k] = value[i];
})

document.write('<pre>' + JSON.stringify(object, 0, 4) + '</pre>');
