JS support timeout and timer. Here is their definition:
timeout – repeat execution of a code within specific time and it returns an integer that can be used to cancel pending timeout.
var timeout_id = setTimeout(f,500);
cleartTimeout(timeout_id);
timer – repeat exectuion of code at specific interval.
id = setInterval(F,5000);
clearInterval(id)
I am a little confused, what is their difference?
setTimeout executes the code only once.
setInterval executes the code at every xxx amount of time.
