Question

i want to know main difference between

Answer 1

SetInterval repeats the call, SetTimeout only runs it once.

Answer 2

setInterval fires again and again in intervals, while setTimeout only fires once.

Answer 3

setTimeout(expression, timeout); runs the code/function once after the timeout setInterval(expression, timeout); runs the code/function in intervals, with the length of the timeout between them

example:

var intervalID = setInterval(alert, 1000); // will alert every second
// clearInterval(intervalID); // will clear the timer

setTimeout(alert, 1000); // will alert once, after a second.

Answer 4

setTimeout():

It is a function that execute javascript statement AFTER x interval.

setTimeout(“do.something();”, 1000); //Execute do.something() 1 second later.

setInterval():

It is a function that execute javascript statement EVERY x interval.

setInterval(“do.somethingElse();”, 2000); //Execute do.somethingElse() every 2 seconds.

The interval unit is in millisecond for both function.
