JavaScript setInterval immediately run

Question

setInterval(function hello() {
  console.log(\'world\');
  retu

Your no longer self-executing the function in your 2nd code snippet. You need to change this to the following:

doMagic: function () {
   setInterval(function magic() {
      console.log('magic');
      return magic;
   }(), 2500);
}

I agree with others though, this isn't the cleanest way to do this and isn't very obvious to the next developer who comes along. I recommend storing the function in a variable, executing it immediately and then running it in the setInterval also:

doMagic: function () {
   var magic = function magic() {
      console.log('magic');
      return magic;
   }
   magic();
   setInterval(magic, 2500);
}
