Why does a JavaScript function fail with certain parameter names?

Question

The following JavaScript function is supposed to make a simple JQuery call to load a page and set a class:

function Lp(page,class) {
    $("#result").load(page);
    $('#nav').attr('class',class);
}

However it failed to work until, on a hunch, I changed the name of the second parameter:

function Lp(page,hilite) {
    $("#result").load(page);
    $('#nav').attr('class',hilite);
}

Surely the parameter names are arbitrary, or am I missing something?

class is a reserved keyword in JavaScript. That's why.
