This course now features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Unlock the full potential of TypeScript with this all-in-one course designed to take you from beginner to confident developer. You'll master foundational concepts, advanced features, and hands-on project development to elevate your coding skills and build robust, type-safe applications. Whether you're transitioning from JavaScript or starting fresh, this course provides the structured guidance you need to succeed. The journey begins with a deep dive into how TypeScript works behind the scenes—from setup and tooling to the transpilation process and its role in modern development. You'll learn multiple ways to run TypeScript across environments like Node.js and browsers, followed by in-depth guidance on using the TSC compiler, PATH configuration, batch scripts, and creating your first functional script. Midway through, you'll set up tsconfig.json, explore modules, and implement bundling, all leading to the heart of the course: a hands-on project. Here, you’ll define types, build interactive DOM elements, validate inputs, manage state, and refactor code with class-based syntax—all while reinforcing best practices in real-world scenarios. Perfect for web developers, JavaScript users, or computer science students looking to scale their skill set. A basic understanding of JavaScript is recommended, but the course caters to both beginners and intermediate learners aiming to level up with TypeScript.
