The settimeout () method is used to call a function or evaluate an expression after a specified number of milliseconds.
Grammar:
SetTimeout (CODE,MILLISEC)
Parameters:
Code (required): The JavaScript code string to execute after the function to be invoked.
Millisec (required): The number of milliseconds to wait before executing code.

{
var t=settimeout ("Alert (' 5 seconds! ')", 5000)
}
