javascript interval

Question

How can I use interval in js? For example I want to call a function every 5 seconds?

Answer 1

setInterval(function(){
  /* your code here */
}, 5000);

And if you need to pass data to the function, you can do it with a closure:

setInterval(function(param){
  return function(){
    console.log(param);
  };
}("hello"), 5000);

will print "hello" to the console.
