About this Course

Learn the basics of the ECMAScript 2015, also known as ES6, JavaScript standard. JavaScript has come a long way since it’s inception in 1995. The ECMAScript 2015 specification brought a lot of improvements, the largest set of changes the language has seen to-date.

In this course, we’ll review some of the new features and demonstrate how they can be used to build better JavaScript applications.

What you'll learn

  • Variable declaration with let and const
  • Arrow Functions
  • Destructuring
  • Data Structures
  • Classes

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.

Classes

JavaScript has always had a prototype-based inheritance system and the introduction of classes does not change that. In this stage, we’ll review how to use the new class syntax to improve the readability of our code.
