Angular developers
You’re using Angular 2+ and TypeScript every day, but it still feels like “framework-required magic.” This is for you if you want to understand what you’re actually writing and why it works.
[LEGACY] Understanding TypeScript
Don't limit the usage of TypeScript to Angular! Learn the basics, its features, workflows and how to use it!

Course Overview
About This Course
You’ve probably bumped into TypeScript through Angular 2+ and ended up using it because “that’s what the framework wants.” But when the errors get cryptic or the syntax feels like extra ceremony, it’s hard to tell what TypeScript is really doing for you.
This course clears that fog by walking you through TypeScript as a language—starting with the core idea that makes it valuable, then steadily layering in the features and the setup choices you’ll actually face in real projects. Along the way, you’ll connect the dots back to the code you write in Angular 2+.
By the end, you’ll be able to confidently add TypeScript to your own work—not just in Angular, but across different stacks. You’ll know how to structure code, configure a workflow, and make TypeScript play nicely with existing JavaScript so you can ship with more confidence and fewer surprises.
What You'll Learn
A focused path through TypeScript language features, compilation, and real-world integration—ending with workflows and usage in ReactJS and Node/Express.
Use types effectively
Write TypeScript that uses types to catch mistakes early and make intent obvious. You’ll be able to choose and apply types in a way that improves everyday JavaScript code instead of fighting it.
Understand compilation output
Explain how the TypeScript compiler works and what it produces when compiling down to ES5. You’ll be able to reason about what runs in the browser or Node after compilation.
Apply ES6+ features
Use next-gen JavaScript features inside TypeScript—like destructuring and arrow functions—without guessing how they behave. You’ll be able to adopt modern syntax while keeping compatibility goals in mind.
Build with core constructs
Create maintainable code using classes, interfaces, generics, decorators, and modules/namespaces. You’ll be able to pick the right construct for the job and keep larger codebases organized.
Integrate JS libraries
Bring third-party JavaScript libraries into a TypeScript project without losing type safety. You’ll be able to wire up external code so your editor and compiler can still help you.
Set up TS workflows
Configure both a plain TypeScript workflow and a Webpack-based setup for real development. You’ll be able to choose a workflow and get it running for your project’s needs.

Prerequisites
Basic JavaScript familiarity is helpful (you should be comfortable reading and writing JS code).
Who Is This Course For?
JavaScript developers
You build in plain JavaScript and want stronger tooling and safer code without abandoning the JS ecosystem. This course fits if you want TypeScript to be a practical upgrade, not a detour.
React/Node builders
You’re working with ReactJS and/or Node/Express and want to bring TypeScript into those projects confidently. This is the next step if you’re ready to standardize on TypeScript beyond Angular.
