Practice

Take your first steps into the wide world of JavaScript and walk away with the core skills needed to become a professional JavaScript programmer!

Build a complete single-page application from scratch using only the browser's own APIs. DOM manipulation, SPA routing, web components, shadow DOM, and reactive programming with Proxies.

Go deep into the foundational mechanics of JavaScript — from execution context and closure to asynchronous code and object-oriented programming.

A deep dive into how browsers actually work under the hood. DOM, CSSOM, WebCore, data synchronization, one-way data flow, and building a custom Virtual DOM from scratch.

Stop building chat wrappers. Learn the discipline of AI engineering by building a real agentic diagramming app from first principles — agents, tools, evaluation, and memory.

Object-oriented design, design patterns, class diagrams, schema design, and machine coding interviews — from theory to full working systems.

Build MCP servers from scratch — registering tools, resources, and prompts; connecting external APIs; SSE and Streamable HTTP transport; and integrating MCPs into Claude Desktop and Claude Code workflows.

Deep dive into React internals — Fiber, lanes, render phases — and practical optimisation techniques like state colocation, memoization, useTransition, and optimistic UI.

Understand how AI prediction and neural networks work under the hood. From basic decision models to production-ready neural networks, build robust mental models for data preprocessing, probability, training, and prediction.

Understand how product decisions get made — and why it matters for every engineer. Learn prioritization, user thinking, A/B testing, PM tools, and product analytics through real case studies.

System design fundamentals — DNS, load balancing, consistent hashing, caching, CDN, and designing at scale from first principles.
