Question regarding missing semi-colon on printToTen()

It's to my understanding that you should end any variable declarations with a semi-colon. I noticed that this workspace & video omit the semi-colon for the printToTen variable declaration, in the refactor.js file.

How come this doesn't throw an error/why is it okay to omit the semi-colon? Thanks in advance!

In JS semi-colons are optional and the interpreter will automatically 'insert' semi-colons where needed. This article does a good job of explaining the concept:
