Answer 1

Since you're including jQuery, you can use jQuery.map in a similar fashion to Linus' answer:

var result      = [],
    status_name = ["a","b","c","b","e","f"],
    status_id   = [1, 2, 3, 4, 5, 6];

result = $.map(status_name, function (el, idx) {
    return [[el, status_id[idx]]];
}); 

Looking at your variable names, I'd guess that your coming from a language (like PHP). If that's the case, make sure you remember to declare local variables with the var keyword, otherwise you'll be polluting the global scope and you'll run into some hideous bugs in IE.

JavaScript has no buitin method for this, but you can easily write it yourself:

function zip(arrayA, arrayB) {
    var length = Math.min(arrayA.length, arrayB.length);
    var result = [];
    for (var n = 0; n < length; n++) {
        result.push([arrayA[n], arrayB[n]]);
    }
    return result;
}

The name zip is chosen because a function that does something like this is often called zip in other languages.
