JavaScript Debug Arrow Function Expressions

Isn't there suppose to be a ; at the end of the second Arrow Function? Since its also considered a Function Expression?

OR is placing a semicolon at the end of an Arrow Function optional?

The use of a semicolon after a statement at the end of a line is always optional in JavaScript.

However, it is considered a "best practice" to use it. And yes, it would be good to include them after the arrow function assignments shown in these examples.
