Build Your First Component

This course takes you from zero React knowledge to confidently building interactive components. Every lesson opens in the Code350 Workspace where the code is already loaded, the video plays beside your editor, and an AI tutor guides you through exercises using only the concepts you've learned so far. You'll start with JSX and component structure, then progressively add props, state, event handling, conditional rendering, and list rendering. By the end, you'll build a complete todo app from scratch — not by copying code from a video, but by writing it yourself with guided AI support. No prior React experience needed. Basic HTML, CSS, and JavaScript knowledge is assumed.
