There are going to be times when you need to skip a single loop or stop a loop from running altogether. It’s possible to do this with variables and if statements, but there is an easier way.

The continue keyword stops the execution of the current loop and starts a new loop. The post loop logic runs, and the loop condition statement gets evaluated.
