Description
This isn’t just another TypeScript course—it’s the most up-to-date, comprehensive course available, fully updated in 2025 to align with the latest version of TypeScript and the most modern development practices.
And yes, I’ll teach you TypeScript from scratch! Whether you’re a beginner or an experienced JavaScript developer, this course covers everything you need to master TypeScript.
You'll learn all the essential concepts, including:
Type Declarations & Inference – Understand how TypeScript manages types dynamically
Interfaces & Type Aliases – Create structured, reusable code with confidence.
Classes & Object-Oriented Programming (OOP) – Master encapsulation, inheritance, and polymorphism in TypeScript.
Decorators (Stage 2 & Stage 3) – Implement powerful meta-programming techniques in your projects.
Generics – Write scalable, reusable functions and components.
Mapped & Conditional Types – Take type safety to the next level.
Modules & Namespaces – Organize and structure your code efficiently.
TypeScript Compiler (tsc) & Configuration – Learn how TypeScript compiles into JavaScript and how to configure it for different environments.
Advanced TypeScript Features – Utility types, infer keyword, keyof operator, and template literal types.
The Inner Workings of TypeScript – Go under the hood to understand how TypeScript interprets and enforces type safety.
And Lots More (See Curriculm for extensive list)
This course isn’t just about learning TypeScript in isolation. You’ll also apply it to build real-world applications using the latest tools and frameworks:
Frontend Development – Use TypeScript with React, ShadcnUI, TailwindCSS, and TanStack Query.
Backend Development – Build a robust Node.js API with Express, Mongoose, and MongoDB using TypeScript
By the end of this course, you’ll have mastered TypeScript in its entirety, gaining the skills to write scalable, high-performance applications that follow industry best practices.
This course contains 300+ Videos which in total contain more than 25 hours of content. I teach you the latest features of TypeScript in a very practical manner providing you with the in-depth knowledge you need to master TypeScript.
Once we are through with the theoretical part of the TypeScript and we understand the intrinsics of the language, we set off to build a full stack application. We build a task management application where you can create a new task and set the priority as well as the status of the task. We also build real-time task counters and work on a complete server state synchronization.
While building the front end of this application, you learn how to use TypeScript with React, ShadcnUI and Tanstack Query. And, when we build the REST API with Node as a backend service for the application, we get practical hands-on experience on how to use Typescript in conjunction with NodeJS along with Express, Mongoose, and MongoDB database. If you are a full-stack developer, you can enjoy and build the complete project with me. And of you, skillsets are limited to the backend or front-end. You can choose the module based on your skills as these modules are self-contained and do not have a dependency on each other.

Why You Should Learn TypeScript
TypeScript is a strongly typed programming language that builds on JavaScript. TypeScript is a superset of JavaScript and can be used along with JavaScript, allowing slow and steady upgradation. TypeScript has been voted the second most loved programming language in the Stack Overflow 2020 Developer survey.
Since the introduction of NodeJS to the community a decade ago, JavaScript has become the most widely used cross-platform programming language. While the size, scope, and complexity of JavaScript programs have grown exponentially, the JavaScript language's ability to express the relationships between different entities of code has not. The most common errors that programmers make are type errors: a specific type of value was used when a different type of value was expected. This could result from simple typos, a failure to understand a library's API surface, incorrect assumptions about runtime behavior, or other errors. TypeScript's goal is to be a static type checker for JavaScript programs.
Apart from providing type checking and strict types, TypeScript comes with a bunch of features that help you to write Object Oriented Code. These features are specific to TypeScript and do not exist in JavaScript.
Who Should Take This Course?
If you are an existing JavaScript developer and want to up your JavaScript game with TypeScript. This course is a perfect fit for you.
If you already have some basic TypeScript knowledge and want to dive deep into advanced concepts. This course is a perfect fit for you.
If you want to learn how to use TypeScript and existing technologies such as React, ShadcnUI, Tanstack Query, Node.js, Mongoose and MongoDB. This course will help you learn TypeScript in conjunction with these technologies.
Who Should Not Take This Course?
Since TypeScript is a superset of JavaScript, this course is not for you if you have never worked on JavaScript. You do not need to be an expert at JavaScript but should have some basic knowledge of JavaScript to benefit from this course.
Suppose you are a new programmer looking for your first programming language course. Then this course is not for you. Since TypeScript builds up on JavaScript, some prior knowledge of JavaScript programming is needed to be able to take this course.
Who this course is for:
- A JavaScript developer who wants to learn TypeScript
- Developers who have NO prior experience with TypeScript
- A beginner TypeScript developer who wants to learn TypeScript
- Developers who want to use TypeScript with front-end frameworks like React JS and Material UI
- Developers who want to use TypeScript for backend REST API development with NodeJs and TypeORM
Instructor
I am a Geek by birth. At the age of 12, I got my first computer, and at the age of 14, I burnt the processor because I inserted a faulty RAM into the motherboard. Technology excites me, and I have a passion for it. Every day I want to dig deeper and understand how a particular technology works.
I worked for hundreds of clients in the past and with skillset and practice am at a stage in life where I'm choosy about what I work on and whom I work with.
I started posting a few posts on my public profile a year and a half ago on Instagram (All related to software development) and got a tremendous response from my followers. I engaged in numerous discussions with people on Instagram. I realized how important it is to contribute to the developer community, which has taught me so much over the years and made me who I am today.
That's how I started Cloudaffle? and intend to spend most of my time on it. I want to go out and teach whatever I have learned and guide budding software developers to be on the correct path of learning and building fanatic software. Cloudaffle is all about technology. So it has tutorials, discussions, videos, live streams, and lots more, all revolving around computing and recent trends that you need to know about it.
