Hello Tal

The const keyword is used when you don't want the identifier to be reassigned. Const doesn't replace var but you can use let interchangeably with var. Also Const and Let give more specific scope. Hopefully I was able to help you! Happy Coding

Hi Tal,

The const keyword was introduced in ES2015. Treehouse does have an Introduction to ES2015 course. This course will cover all the changes to JavaScript with the ES2015 introduction.
There is also a a very quick (14 minutes) Workshop here that covers Defining Variables with Let and Const.

For now, I'd recommend at least doing the Workshop. Then if JavaScript is a path you are wishing to go down, the ES2015 course would be a next logical choice.

Keep Coding! :) :dizzy:
