Overview

About this course

Learn the language that powers interactive websites, starting from the very beginning. Over five days you will see how JavaScript runs, then work with variables, data types, objects, arrays and operators, and interact with users through simple dialogs.

Each topic follows the published JSE content outline, and practice questions prepare you for the Certified Entry-Level JavaScript Programmer exam.
