Set a delay for a specific function.
ID = window.setInterval("funcName", delay)
funcName is the name of the function for which you want to set a delay.
delay is the number of milliseconds (thousandths of a second) that the function should be delayed.
ID is the interval ID.
intervalID = window.setInterval("animalate()", 500);
The interval ID is used to refer to the specific interval when it needs to be cleared. The setInterval() function is commonly used to set a delay for functions that are executed again and again, such as animations.
