Certificate in JavaScript

It starts with your first JavaScript on a real page and a site live on GitHub Pages. From there you learn values and decisions, functions, arrays and objects, then take over the page with the DOM and build your first app, a quiz. Forms, debugging, state and storage, and live data from public APIs come next, then a modern toolchain with tests and TypeScript, an accessibility and security audit, and a capstone app for a client brief.

Yes, the basics. You'll be writing code that changes real pages, so you need to know how a page is built, but you need no JavaScript at all. Our HTML & CSS course covers exactly what you need.

No. JavaScript runs in every browser, and the editor, Git, GitHub, Node.js, the testing tools, the screen reader and the public APIs the course uses are all free. The AI assistant you bring in for debugging works on a free tier.

JavaScript if you want to build for the web: it's the language every browser runs, and the one that makes a page interactive. Python if your interest is data, automation or general programming, where it reads more simply. Either makes a good first language, and this one assumes HTML and CSS first.

Not to start. The lessons build one fictional client's site, a small independent cinema in Sheffield, so you always have something real to work on. For the tracker app you pick a use of your own, like job applications, and for the capstone you choose a client brief and add a feature of your own.

Harder than HTML and CSS, because there are more moving parts, and the course takes them one at a time. Each idea goes into the cinema site before the next one arrives, and the OBA Tutor is in every lesson when an error makes no sense.

None, on purpose. The course teaches the plain JavaScript every framework is built on, and shows how a React component compares without teaching React. Learn this properly and React, Vue or anything else becomes far easier to pick up.

Yes. Pass the final assessment and you get an OBA certificate of completion that an employer can verify online. It isn't an accredited qualification or a vendor certification. The apps on your GitHub are the other half of the proof.
