JavaScript
JavaScript is a free 3-week beginner course covering variables, functions, arrays, DOM manipulation, and event handling — the core language every website runs on. Learners progress to asynchronous JavaScript with promises and async/await, closures, and modern ES6+ syntax, building projects like an interactive to-do list and a live search feature.
Use values and conditions. Transform arrays with functions. Respond to a button click.
