Summary

JavaScript is known as the "language of the web." It is a powerful object-oriented language that is lightweight and can communicate with the browser.

We'll introduce you to the core concepts. Each concept has a video tutorial followed by a practical challenge to solve.

Getting started

To run this exercise you need to have installed the correct software using the Bootcamp Computer Set Up Guide instructions during Sprint 1.

Tip: these challenges will introduce you to some new terminology. You might find it helpful to have the JavaScript Glossary open as an additional resource while you work through them.
