Is it bad to use setInterval?

In case of time intensive synchronous operations, setTimeInterval may break the rhythm. Also, if any error occurs in setInterval code block, it will not stop execution but keeps on running faulty code. Alternatively, you can use setTimeout recursively in case of time sensitive operations.

What is the return value of setInterval?

The setInterval() returns a variable called an interval ID.
