Getting Started With ES2015 Course (How To)

ES2015, also called ES6, is a newer version of the JavaScript language that’s well supported in browsers and commonly used by programmers.

In this course, you'll get up-to-speed with ES2015 basics and be well on your way to writing modern JavaScript. You'll learn best practices for creating variables, using the let and const keywords, and a better way to concatenate string values using template literals. You'll also learn the compact syntax for creating functions using "arrow syntax."

What you'll learn

• Defining variables with let and const
• Concatenating strings with template literals
• Creating arrow functions

Defining Variables With let and const

For most of JavaScript's life, there's been only one way to create, or "declare", a variable: the var keyword. In the latest version of JavaScript there are two new ways: const and let.
