I found this excellent jsfiddle that helped me:

In my case I needed throttle because a function (which was a server request) was being called about 500 times in 1 second, and was overloading the server. So I changed it so that the function could only be called max once per 3 seconds. So it doesn't matter how many times it's called, it'll only occur once per 3 seconds max.

Something like this:

var informationFromServer;
var a = _.throttle(function(){
    informationFromServer = serverCallFunction();
}, 3000);

function getsCalledALot()
{
    a();
}

function serverCallFunction()
{
    var data = $.post....
    return data;
}
