The window object allows execution of code at specified time intervals.

These time intervals are called timing events.

The two key methods to use with JavaScript are:

• setTimeout(function, milliseconds)
  Executes a function, after waiting a specified number of milliseconds.
• setInterval(function, milliseconds)
  Same as setTimeout(), but repeats the execution of the function continuously.

The setTimeout() and setInterval() are both methods of the HTML DOM Window object.
