Learn React.js with TypeScript
In this course, you will learn React with TypeScript to build interactive user interfaces. You will create components, manage state with hooks, fetch data from APIs, and build multi-page applications.
React changed how developers build for the web. Instead of writing one big page, you build small, reusable pieces that come together like LEGO. Over 3 months, you'll learn to think in components, manage application state, and build the kind of interfaces that companies like Meta and Airbnb ship to millions of users.
Why learn React?
React is used by over 40% of developers worldwide , more than any other UI library. Companies like Meta, Netflix, Airbnb, and thousands of startups build their products with it. When you learn React with TypeScript, you're learning the exact stack that hiring managers are looking for. This isn't theoretical , it's the most direct path to getting hired as a frontend developer.
Before React, developers wrote monolithic pages where HTML, CSS, and JavaScript were tangled together. React changed that: you build small, self-contained pieces and compose them into complex interfaces. This approach scales from simple widgets to applications used by millions, and it's how the best teams work today.
What you'll be able to do
By the end of this course, you'll have the skills and projects to prove it.
Build interactive UI components
Create buttons, forms, cards, and layouts with props and state. Each component updates automatically when data changes, no manual DOM manipulation needed.
Fetch data from APIs and display it live
Connect your apps to external services, handle loading states, and build the kind of data-driven interfaces that real products use.
Manage state across your entire app
Use useState, useEffect, useContext, and custom hooks to share data between components without prop drilling or messy global variables.
Build multi-page applications with routing
With React Router, you'll navigate between pages, handle URL parameters, and build nested routes, the same patterns used in dashboards and e-commerce sites.
Course Outline
3 months of structured learning. Each module builds on the previous one, so you develop skills in the right order.
React Fundamentals
Understand the component-based thinking that makes React powerful. You'll build reusable UI pieces, manage their state and props, and learn the patterns that make React codebases maintainable at scale.
Hooks and Side Effects
Master the hooks that bring your components to life. You'll handle side effects like data fetching, manage complex state with useReducer, optimize performance with useMemo, and build custom hooks that keep your code clean and reusable.
Patterns and Best Practices
Learn the patterns that separate production code from tutorials. You'll handle forms, manage state beyond props, write tests, and apply the conventions that make your React code feel professional and maintainable.
Potential Job Opportunities
With React skills, you'll qualify for these roles. Each one is in active demand across Nigeria and internationally.
Frontend Developer
React is the skill that gets you in the door for most frontend roles. You'll build the interfaces that users interact with every day, from dashboards to e-commerce sites to social platforms. This is the most in-demand frontend role in the industry.
Full-Stack Developer
React on the frontend, a backend framework on the server. Full-stack developers who know React can own features end-to-end, which makes them invaluable to startups and small teams that need people who can handle the whole picture.
Web Developer
Build and maintain websites and web applications using React. React is the most popular frontend library, and developers who master it are in constant demand across every industry.
React Native Developer
Use your React skills to build cross-platform mobile apps. React Native lets you write once and deploy to both iOS and Android, and companies increasingly prefer this approach over maintaining separate native teams.
Freelance Developer
Start your own web development business. With React skills, you can take on diverse projects, from single-page applications to complex web apps, and set your own rates and schedule.
Is this for you?
If any of these sound like you, this course was designed with you in mind.
You've completed HTML/CSS and JavaScript
React builds directly on what you've learned. If you can write JavaScript and manipulate the DOM, you're ready for React.
You're switching careers and want the best shot
React has the largest job market of any frontend framework. Learning it gives you the widest range of opportunities when you start applying.
You want to build your own product
React's component model makes it ideal for building everything from landing pages to full web applications. You'll have the skills to ship your own ideas.
What our graduates say
Real words from people who took this exact course. No scripts, no incentives for reviewing.
“I had built a few static sites and knew JavaScript but React felt like a completely different world. The course made it manageable. Components, hooks, state management, it all started clicking around week four. I built a full multi-page app by the end.”
David O.
WD401 Graduate
“What surprised me was how much I enjoyed it. I expected React to be frustrating. Instead, building components felt like solving puzzles. The instructor was patient and always had a real-world example ready when a concept felt abstract.”
Fatima A.
WD401 Graduate
“I applied for three frontend roles two weeks after finishing this course. The portfolio projects from class were more impressive than anything I had built on my own. Got my first offer within a month.”
Chidi E.
WD401 Graduate
“React hooks made sense for the first time in this course. I had watched dozens of YouTube videos but nothing stuck until I had to build with them live. The hands-on approach is what makes this course work.”
Aisha R.
WD401 Graduate
“The React Router section was a game changer. I went from building single-page apps to understanding how real applications handle navigation. That knowledge alone elevated everything I build now.”
Tobi L.
WD401 Graduate
“I was nervous about the pace since I work full time. But the schedule is manageable and the instructor is responsive outside class. I never felt lost. By the end I had three portfolio projects I'm genuinely proud of.”

How are the classes delivered?▼
Classes combine live sessions, practical assignments, guided review, and supporting resources so learners can keep practicing outside class time.
What if I miss a class?▼
Where replays or resources are available, you can use them to catch up. You can also ask questions during review windows or support sessions.
Do I get a certificate after completion?▼
Yes. Learners who complete the required modules and projects receive a certificate of completion.
What is the cohort size?▼
Each cohort is limited to 7 students to ensure personalised attention and feedback.
Do I need prior coding experience?▼
Yes. You should be comfortable with HTML and CSS, JavaScript, and ideally TypeScript before starting this course. If you need to build those skills first, our individual courses will get you ready.
Do I need to know TypeScript before React?▼
Not strictly, but it helps. This course teaches both together, with TypeScript integrated into every React concept from the start.
What is the difference between React and Next.js?▼
React is a library for building UIs. Next.js is a framework built on React that adds server-side rendering, routing, and API features. This course focuses on React fundamentals first. Once you're comfortable with React, our Next.js course is the natural next step.
