"no links i have already checked"

Tough! :laugh:
You clearly either haven't checked too well, or you didn't read what you found.
A very simple google for the setTimeout function takes you straight to w3Schools: http://www.w3schools.com/jsref/met_win_settimeout.asp[^] - which tells you exactly what it does, and even gives you examples!

A small bit of reading, and it should all make sense.
