Javascript is single-threaded  so by nature there should not be a sleep function because sleeping will block the thread  setTimeout is a way to get around this by posting an event to the queue to be executed later without blocking the thread  But if you want a true sleep function  you can write something like this   function sleep miliseconds       var currentTime   new Date   getTime        while  currentTime   miliseconds  gt   new Date   getTime               Note  The above code is NOT recommended

There s no  safe  way to pause execution  You can  however  do something like this using setTimeout   function writeNext i        document write i        if i    5          return       setTimeout function                 writeNext i   1           2000      writeNext 1

There s no way to stop execution of your code as you would do with a procedural language   You can instead make use of setTimeout and some trickery to get a parametrized timeout    for  var i   1  i  lt   5  i          var tick   function i            return function                 console log i                        setTimeout tick i   500   i       Demo here  http   jsfiddle net hW7Ch

You can use setTimeout to do this  function myFunction            your code to run after the timeout       stop for sometime if needed setTimeout myFunction  5000
