In this lesson we begin our journey into ES6 by looking at how we can declare variables. In the past, javascript has allowed us to declare variables using the "'var" keyword. This is not the greatest way to declare a variable because we do not always want to declare the same type of variable, and we may want to declare a variable that never changes. There are many reasons for not wanting to use one keyword all the time for declaring variables and ES6 has allowed for us to declare a variable and only use that variable within the scope of reference using the "let keyword"'.
