Ten Weeks to a Real App: A Hands-On JavaScript Course for High School

By Adam Seebeck

Ten weeks. One real app. Built from an empty folder.

Most beginner coding books stop at toy exercises. This one ends with something your student can put on the internet and hand to somebody.

Over twenty chapters, students in grades 9 through 12 build an interactive Sherlock Holmes case file that runs in a browser. They pick a case, read the client's account, and examine a scene drawn on canvas. Clues they collect decide which deductions unlock, so the interface changes as they work out what happened. Case data comes from a file they write themselves. Solved cases are remembered between visits.

Then they close that project and build something entirely of their own, from an empty folder, using only what they now know.

What is inside

Plain HTML, CSS, and JavaScript. No frameworks, no build tools, no command line.A free editor and a browser are the only software required.Real terms used properly: callbacks, scope, return values, the event loop, coordinate space, hit detection.Canvas drawing, pointer and keyboard interaction, JSON, and saved progress.Three practice exercises and a quiz in every chapter, with a full answer key.A chapter on reading AI-generated code and judging it rather than trusting it.A final chapter on testing, debugging, and what never goes on a page a young person publishes.

Paced for a school term. Works in a classroom, at a homeschool table, or on a laptop at the kitchen counter.
