Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026

The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.


We’ve talked about objects before.

Object oriented programming takes objects at a whole new level.

In this unit you’ll discover classes, how to create methods, what are constructors, how to use inheritance, and then we’ll talk about one of the most confusing (but fundamental) aspects of JavaScript: prototypes.
