Unary Operators

Unary operators are ++ and –. Each of these either increment by one or decrement by one. It is important to understand how these interact with variables because they can be placed prior to or after a variable. For example…

let year = 2020; 

This would log out 2021. Let’s change it a bit…


The value 2020 would be logged out because the amount would not be incremented until after it prints out. If we were to console log out the “year” variable again, it would display 2021. The minus symbols (decrement) works the same way.

Happy Coding!
