JS: A better interval handler

interval.js

/**
 * setInterval has some issues:
 * 1. Doesn't care whether the callback is still running or not
 * 2. Ignores errors
 * 
 * @source http://www.thecodeship.com/web-development/alternative-to-javascript-evil-setinterval/
 * @param func  The function to call
 * @param wait  The interval to wait
 * @param times The total number of repititions, instead of infinite
 * 
 */
function interval(func, wait, times){
    var interv = function(w, t){
        return function(){
            if(typeof t === "undefined" || t-- > 0){
                setTimeout(interv, w);
                try{
                    func.call(null);
                }
                catch(e){
                    t = 0;
                    throw e.toString();
                }
            }
        };
    }(wait, times);

    setTimeout(interv, wait);
};

// Usage: 
interval(function(){
    // Code block goes here
}, 1000, 10);
