Course Overview

Build the Full Spectrum of Modern Frontend

Frontend development is the discipline of turning code into everything a user sees and interacts with in a browser — HTML structure, CSS presentation, JavaScript behaviour, and the frameworks and tooling that tie them together at production scale. This track covers the complete stack: from how the web delivers a page to writing type-safe React and Vue applications, optimising performance, and deploying through a CI/CD pipeline.

What You Will Learn

You will start with HTML, CSS, and JavaScript fundamentals, then gain fluency in TypeScript, the DOM and Browser APIs, responsive design, and ES6+ patterns including async programming and modules. From there you move into React (hooks, advanced patterns, Next.js SSR) and Vue 3 (Composition API, Nuxt 3 SSR), state management, frontend testing, CSS architecture, and real-time interfaces with WebSockets. The track closes with web performance optimisation, frontend security, design systems, and frontend CI/CD and DevOps.

The Learning Path

Forty-one courses span levels A1 through C2. The A1 and A2 courses establish the foundations — how the web works, semantic markup, CSS animations, Git, and TypeScript introduction. B1 and B2 courses build professional competence: CSS Layout Mastery, JavaScript Modules and Build Tools, React and Vue 3 fundamentals, API integration, Progressive Web Apps, and Server-Side Rendering with both Next.js and Nuxt 3. The C1 courses handle senior-level concerns: Advanced TypeScript for Frontend, React Advanced Patterns, Vue Advanced Patterns, Frontend Architecture, Design Systems and Component Libraries, Frontend Security, and Frontend CI/CD and DevOps. The track ends at C2 with Senior Frontend Engineering, which consolidates everything into production-grade practice.

How It Works

Each course is split into short, hands-on lessons you complete in the built-in code editor with real-time feedback. An AI tutor is available whenever you get stuck, and every concept is reinforced through exercises that reflect real browser and framework behaviour rather than contrived examples.
