JavaScript setTimeout and setInterval: Difference between setTimeout and setInterval Methods
Both setTimeout and setInterval methods are timer methods with the same syntax. The setTimeout method is used to execute a function after a specific delay and the setInterval method is used to execute a function repeatedly at specified intervals.
In this video, we update a slider using setInterval and setTimeout methods. You could find that the setInterval method updates the slider at specified intervals whereas the setTimeout method updates the position of the slider just once after the specified delay.
Once the timer is of no use, then you should clear the timer using clearInterval method in case of setInterval method and using clearTimeout method in case of clearTimeout method.
To see how to use the setInterval method to create a clock, see this video:
