What you'll be able to do
- Understand where JavaScript runs, what it does that HTML cannot, and write your first lines in the browser console.
- Make code choose between paths with if/else and repeat work with loops — the two structures inside all programming.
- Hold many values in arrays, describe one thing with an object, and package reusable work into functions.
- Select elements, react to clicks and input, and change the page — the browser skills that make JavaScript visible.
- Read and write JSON, fetch data from a URL, and render a list onto the page — the front half of every real web app.
- Assemble the course into one small complete app, learn the habits that survive, and see exactly what the paid courses add.
