JavaScript Mapping key/value with javascript mapping key value,elasticsearch mapping key value,javascript mapping key

Is there any way to map keys and values ​​in an array using Javascript? In my opinion, it is something similar to jQuery .map(), but instead of mapping only the value, also "maps" the keys.

Suppose I have the following array:

var names = [ 1, 2, 3, 4, 5 ];

And I like to use a function called numberToName() that I created and generate another array from this, and the result should be something like this:

var names = { "one": 1, "two": 2, "three": 3, "four": 4, "five": 5 };

Currently I use the following method:

var names = [ 1, 2, 3, 4, 5 ],
    names_tmp = {},
    names_i = 0,
    names_len = names.length;

for(; names_i < names_len; names_i++) {
    names_tmp[numberToName(names[names_i])] = names[names_i];
}

The question is: is there any way (preferably native) to improve this method? I could even use jQuery without problems. Perhaps a function similar to this:

var names = jQuery.mapKeys([ 1, 2, 3, 4, 5], function(k, v) {
    return { key: numberToName(v), value: v };
});
