setTimeout() - Web APIs.
The setTimeout() method executes a block of code after the specified time. The method executes the code only once. The commonly used syntax of JavaScript setTimeout is: setTimeout(function, milliseconds);

The setTimeout() is executed only once. If you need repeated executions, use setInterval() instead. Use the clearTimeout() method to prevent the function from starting.
