Episode 1 Checklist: What to Master Before Episode 2

Episode 1 Checklist: What to Master Before Episode 2

Episode 1 of any React course looks easy, and that is exactly why learners rush past it. Before moving to Episode 2 and its bundlers, npm, and project structure, make sure you genuinely understand the following.

You Can Explain What React Is

In your own words, without copy-pasting a definition, explain what React is and what problem it solves. If you cannot, you have not internalized it.

You Understand the Difference Between React and ReactDOM

React defines the UI; ReactDOM connects it to the DOM. If that distinction is fuzzy, the rest of the course will be fuzzy too.

You Have Rendered Hello World via CDN

Not by copying, but by writing it from scratch and explaining each line: the scripts, the root element, createRoot, and render.

You Understand JSX at a Basic Level

You know JSX looks like HTML but compiles to JavaScript, and you can name at least one difference between JSX and HTML, like className.

You Can Describe the Rendering Flow

You can explain the path from writing JSX to seeing DOM nodes: compile to an object, ReactDOM turns it into DOM, state changes produce new descriptions.

You Hit and Fixed at Least One CDN Error

You ran into something like a script order issue or a missing Babel script, and you fixed it yourself. Errors teach more than success.

Why This Checklist Matters

Episode 2 builds directly on Episode 1. If you move on with a shaky foundation, every later episode feels harder than it is. Spend an extra hour nailing Episode 1 and save yourself days later.

The Takeaway

Rushing through the basics is the most common beginner mistake. Use this checklist honestly. If you cannot tick every item, do not move on yet.
