interval.js

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);
