Introducing ES2015 Course (How To)

ES2015 Basics

Because JavaScript has a hard requirement to be backwards compatible with older specifications, you can safely continue using what you already know today. However, ES2015 comes with helpful features, like variable and function scoping, which are common in other programming languages.

In this stage, we’ll look at the new let and const variable declarations as well as play with string functions new to the language.
