Will setInterval cause browsers to hang?

Question

A couple years ago I was warned against using setInterval for long periods of time as it supposedly would cause the browser to hang if the called function ran l

Answer 1

it always better to use setTimeout in a loop so you know exactly when to continue timing:

foo();
function foo(){

   setTimeout (function(){
      foo = 'bar_' + i++;
      foo();
     }, 1 );

} 

otherwise as you said above, the browser will have to catch up and since ur loop is in infinitum, it might not.
