JavaScript is the language of the web. If you want to code for the web, you need to know JavaScript inside and out. From humble beginnings, JavaScript has grown to a powerful and complex language with features such as classes, promises, arrow functions, generators, string templates, and many others.

In this course, you’ll learn all of the essential concepts of the JavaScript language. That’s right: all of them! Including the most important recent improvements to the language, in JavaScript ES6 (ECMAScript 2015) and JavaScript ES7 (ECMAScript 2016).

You’ll start with the very fundamentals of the language: variables and datatypes. Then in each lesson you’ll build knowledge, from data structures like arrays and maps to loops, control structures, and functions. Along with the basics of the language, you’ll also learn some key built-in APIs for manipulating data, AJAX, and working with the web browser DOM. Finally, you’ll get a look at some of the most powerful and widely used web APIs that are supported by all modern browsers.

There’s a lot to learn, so let’s jump in!
