A common question from JavaScript beginners is how to call the setTimeout or setInterval function. This is an easy task, but can definitely be a headache for those who are new to JavaScript programming. We recently received this question from a user:

There are a few ways to call the event, but the most efficient solution to execute setTimeout or setInterval functions in the above code would be to use a non-named function. Below is some quick code for this solution:

...
     var tmFunc = function(){ exec(); };
     setTimeout(tmFunc, duration);
     function exec(){
          alert("exec");
     }
...

That’s it ;) Click the Demo button to view this solution in action.
