// Comments are used document your code so it is easier for humans to understand. You should include a comment at the start of each function to explain what the function does, if it takes any arguments, and if it returns any values. It is also a good idea to comment any complex blocks of code so you, or another programmer, can more easily maintain or modify the code in the future.

// Comment

• You can type whatever you want on a comment line.
• You can comment out a block of statements using /* before the first statement and */ after the last statement.
