Program Overview

JavaScript is the only programming language every web browser understands, which makes it the most immediate language a teenager can learn: write a line, refresh the page, and something on screen changes. This 6-month live course starts at zero and builds in one direction, toward work worth showing. Months 1 and 2 cover the language core and the DOM, so pages respond to clicks and typing within weeks. Months 3 and 4 add real data: arrays, objects, JSON, saving with localStorage, and fetching from public APIs such as live weather. Month 5 is games on the HTML canvas, with a proper game loop, keyboard control, and collision detection. Month 6 is the capstone: each student scopes, builds, and deploys an interactive site of their own, then presents it.

Classes are live and small. Students write code in every session while an instructor watches them work, and homework gets reviewed, not just collected.

What Makes This Program Different

  • ✓ Everything runs in the browser students already have, so the write-refresh-see loop takes seconds and motivation stays high
  • ✓ The DOM arrives in month 2, not month 5: pages react to clicks within the first weeks, long before the theory runs out
  • ✓ Real public APIs instead of toy data: weather, dictionaries, and services students choose themselves
  • ✓ A full month of canvas games, because a game you built yourself is the project teens actually show their friends
  • ✓ The capstone is deployed to a real URL, so the finished site can sit on a school application or be sent to relatives
  • ✓ No prior HTML needed: the markup and CSS each project requires is taught in class, exactly when it is needed

Your Learning Journey

Phase 1
The language and the page: variables, decisions, loops, and functions, then the DOM and events so pages respond to users
Phase 2
Data and the network: arrays, objects, JSON, and localStorage, then fetch and public APIs for pages built on live data
Phase 3
Canvas games with a real game loop, then a scoped, deployed capstone site presented to the class

Career Progression

1
A deployed, interactive capstone site plus a folder of working projects to show
2
The exact foundation needed for React, Node.js, and full-stack courses later
3
Comfort reading and debugging real JavaScript, a skill school ICT classes rarely build
4
A head start for school hackathons and computer science electives
