What you'll learn

Write modern JavaScript fluently: variables, types, functions, scope, and error handling
Master the patterns that matter — arrays, objects, closures, `this`, prototypes, and ES6+
Build interactive UIs with the DOM and Web APIs, then handle async with promises, async/await, and fetch
Work like a professional: npm, ES modules, Vite, ESLint/Prettier, env config, and Vitest testing
Add real type safety with TypeScript: basic types, interfaces, generics, utility types, narrowing, and classes
Apply TypeScript end to end across typed projects, API integration, and a JS→TS refactor
Understand how frameworks really work — state, components, pub/sub, and MVC
Ship a deployed, type-safe Expense Tracker capstone and prepare for JS & TS interviews

Requirements

  • No prior programming experience required — the course starts from setup
  • A computer (Windows, macOS, or Linux) and a willingness to practise
  • A few hours per week to follow the lessons, exercises, and projects

Description

JavaScript is the language of the web, and TypeScript is how professional teams keep large JavaScript codebases safe and maintainable. This course teaches both, in the order that actually works: JavaScript first, until it is second nature, then TypeScript layered on top of everything you already know. You start from a blank editor and finish with four real projects — including a deployed, type-safe Expense Tracker — and the confidence to interview for a developer role.

Every lesson pairs plain-English explanation with a clear diagram, runnable code, a hands-on exercise, and a knowledge check, so you are always practising rather than just reading. Nothing is hand-waved: you will understand why const beats var, what a closure really is, how the event loop schedules your async code, and why unknown is safer than any.

How the course is organized

The twelve sections move from setup to a job-ready portfolio:

  • Foundations — developer setup, JavaScript fundamentals, and the intermediate patterns (arrays, objects, closures, this, prototypes, ES6+)
  • The browser & async — the DOM and Web APIs (ending in a To-Do app), then asynchronous JavaScript (ending in a Weather app)
  • Professional tooling — npm, ES modules, Vite, ESLint/Prettier, environment variables, and testing with Vitest
  • TypeScript — the basics (types, interfaces, unions, enums) through advanced features (generics, utility types, narrowing, mapped/conditional types, classes and OOP)
  • Applied & advanced — typed projects, API integration, validation, a JS→TS refactor, and how frameworks really work (state, components, pub/sub, MVC)
  • Capstone & career — a deployed Expense Tracker built end to end, plus JavaScript and TypeScript interview prep, portfolio building, and a next-steps roadmap

Who it's for

Complete beginners who want a structured path into web development, and self-taught developers who can write some JavaScript but want to fill the gaps and add real TypeScript. No prior experience is required — just a computer and a few hours a week. You finish able to build and ship type-safe applications and ready to take the next step into a framework like React or Vue.

Noah has spent 11 years building production web apps in JavaScript and TypeScript — from scrappy startup frontends to design systems and developer tooling at Stripe and Vercel. He has migrated large untyped codebases to strict TypeScript without grinding teams to a halt, and mentored dozens of self-taught developers into their first engineering jobs. He teaches the way he learned on the job: JavaScript until it is second nature, then TypeScript layered on top, always anchored to real projects you can deploy and talk about in an interview.

Mixed feelings — some lessons were excellent, others felt thin. Average overall.
