Introduction to TypeScript

This course is designed for absolute beginners who want to master the basics of the TypeScript programming language. TypeScript is a modern and powerful language that extends the capabilities of JavaScript, making your code more reliable and readable. We will start from the very basics, covering variables, data types, comparison operators, and conditional statements. Then, we will delve into working with arrays and loops. Upon completing this course, you will be ready to create simple programs in TypeScript and continue your learning journey into more advanced topics.

Working with Interfaces and Generics in TypeScript

A practical course on mastering interfaces and generics in TypeScript. Learn how to design robust type systems that make your code safer, cleaner, and easier to scale. From defining interfaces to building reusable generic patterns, this course provides a complete foundation for writing modern, type-safe applications.

TypeScript Foundations

Master the essentials of TypeScript and understand how it enhances JavaScript with static typing and modern development features. Build a strong foundation through practical examples, from working with core types to applying advanced type tools. Gain the confidence to write safer, cleaner, and more scalable code in any TypeScript project.

TypeScript Functions and Parameters

Explore how TypeScript enhances function design with precise typing and advanced parameter control. Work with explicit and inferred return types, handle complex parameter setups, and define overloads for flexible function behavior. Understand how this works in different contexts and write functions that are both safe and expressive in modern TypeScript projects.

TypeScript Types Fundamentals

Explore TypeScript's type system, guiding you from the basics of primitive types to advanced concepts like type inference, narrowing, and safe handling of any and unknown. Learn how TypeScript makes JavaScript code safer, more robust, and easier to maintain.

Why People Choose Codefinity

Web Developer

Kwizera Mugisha

The teaching methodology at Codefinity is excellent, and I particularly appreciate how it has prepared me to handle real-world coding problems. Currently, I am delving into Node.js and eagerly anticipate building full-stack projects that integrate all the knowledge I have gained.

Senior Business Analyst

Sherry Barnes-Fox

My first course was 4 hours, I did it in a few days, "nugget-style". The instructions are very clear and easy to understand. There is even a hint to help you get the answer. I love the learning style that is used, it engages me.

Accounts Payable Specialist

Bill Wagner

I have really liked the browser-based lessons that allow me to code within the lesson. The RUN button allows me to test the code I write before submitting for a grade.

IT Support Specialist

Daniel Chinea

I have gained a lot of practical and logical thinking skills, along with patience for myself and confidence in myself that I can learn programming. Years ago, I would have never thought that I could learn programming in any way, shape or form, and I was able to obtain these certifications and skills with Codefinity.

Technology Project Manager

The learning was progressive and made it easy to follow along and make progress. I could feel my skills increasing and building on each other as the course went along.

Project Manager

Stephanie Chan

As I went through the first course of the Python track, I liked the way the course was lay out (in easy and digestible modules) with little exercises at the end of each concept.
