Copy an array into another that already exists (like 'dest = src;', except that it keeps the reference to the existing array)

copyList.js

function copyArray(src, dest)
{
    // (performance: http://jsperf.com/empty-javascript-array & http://jsperf.com/array-extending-push-vs-concat)
    while(dest.length > 0)
    {
        dest.pop();
    }
    if (src)
    {
        for (var i = 0; i < src.length; ++i)
        {
            dest.push(data.Search[i]);
        }
    }
}
