Time based repetition

SetIntervalcanbeajerk.js

//Alternative to setInterval
 
//Set interval will run the function doStuff() every 100ms regardless if doStuff has finished.
setInterval(function(){
doStuff();
},100);
 
 
//Alternatively you can use argements.callee after doStuff(); which will is wrapped in a self invoking anyonomous self invoking function  
(function(){
  doStuff();
  setTimeout(arguments.callee,100);
})();
// arguments.callee calls the parent function, support is wide spreed with no plans of removing but in older browsers for arguments.callee is unreliable
// arguments.callee has been removed from ES5 strict mode
 
 
//You can get around this by declaring the function with a name and calling it within the setTimeout
(function doStuff() {
  // Statements
  setTimeout(doStuff, 100);
})();
