The ! operator returns a boolean value that can be true or false.

!false is true, !true is false.

 

If the data type is not boolean it will be cast to boolean. All numbers are considered true except zero. All strings are true except an empty string.

If timer_is_on is 0, then !timer_is_on is true, if timer_is_on is any number other than 0 then !timer_is_on is false.

Did you edit your question or something to ask something completely different? You shouldn't do that, just make a new post. Among other things, if you edit your question it doesn't let anyone know that there is a new unread post to look at.The only difference between setInterval and setTimeout is that using setTimeout will only run the code once after the certain amount of time, while setInterval will keep running the code after the interval until you stop it. Everything else works the same.

the difference is well documented in the tutorials

The setInterval() method calls a function or evaluates an expression at specified intervals (in milliseconds).

 

The setInterval() method will continue calling the function until clearInterval() is called, or the window is closed.

The setTimeout() method calls a function or evaluates an expression after a specified number of milliseconds.

 

 

Tip: The function is only executed once. If you need to repeat execution, use the setInterval() method.
