Level 3 will cover React with lots of JavaScript and functions. This self-paced lesson helps you get comfortable with functions and how they can be used to build UI.
In particular, you’ll learn the Update Screen pattern, which is a fundamental concept that centralizes UI updates in a single function.
This pattern makes your code more organized, predictable, and easier to debug—skills that will be essential as you transition to React development.
