Access every other item in an array - JavaScript

Question

Is it possible for me to access every other item in an array? So basically, all items in positions 0, 2, 4, 6 etc.

Here\'s my code if it helps:

If you just want this with lineLength and not with key, then add a second variable and use += when incrementing:

function pushToHash(key, value) {
    for (var t = 0, x = 0; t < value.length; t++, x += 2) {
        MQHash[key[t]] = value.slice(0, lineLength[x]);
    }
}

(The power of the comma operator...)
