Master JavaScript from basics to advanced
Learn proven techniques to prevent JavaScript memory leaks using WeakMap. Covers common leak patterns, DOM reference management, listener cleanup, private data with automatic disposal, cache eviction, observer pattern memory safety, and debugging strategies.
Master JavaScript generators for lazy evaluation, coroutines, and async control flow. Covers generator functions, yield expressions, iterator protocol, delegation with yield*, infinite sequences, two-way communication, async generators, cancellation patterns, and real-world pipeline architectures.
Master async control flow using JavaScript generator functions. Covers coroutine runners, sequential and parallel execution, error propagation, cancellation tokens, retry logic, resource cleanup with finally, saga patterns, and building your own async/await with generators.
Master the JavaScript iterator protocol for custom collection traversal. Covers Symbol.iterator, iterator result protocol, iterable consumers, lazy iterators, stateful iteration, bidirectional iterators, composable iterator utilities, and integration with destructuring, spread, and for-of.
Learn to build custom iterable data structures in JavaScript. Covers linked lists, trees, graphs, skip lists, priority queues, circular buffers, infinite streams, range objects, and bidirectional iterables with complete Symbol.iterator implementations.
Master JavaScript metaprogramming for dynamic, self-aware code architectures. Covers Proxy meta-object protocol, Reflect API integration, Symbol-based protocols, property descriptors, dynamic class creation, aspect-oriented programming, DSL construction, and compile-time vs runtime metaprogramming.
Explore self-modifying JavaScript patterns for adaptive, optimizing architectures. Covers function replacement, hot-path optimization, lazy initialization, adaptive algorithms, plugin hot-reloading, self-patching APIs, runtime code generation, and safety guardrails for production use.
Build a modern UI framework from scratch in JavaScript. Covers virtual DOM implementation, diff algorithms, reactive state management, component lifecycle, template compilation, event delegation, batched rendering, hooks system, server-side rendering, and hydration.
Master JavaScript code generation techniques for compile-time and runtime metaprogramming. Covers AST manipulation, Babel plugin authorship, tagged template literals as macros, code generation pipelines, source-to-source transformation, compile-time evaluation, and safe eval alternatives.
Master Web Workers for truly parallel JavaScript execution. Covers dedicated and shared workers, structured cloning, transferable objects, SharedArrayBuffer with Atomics, worker pools, task scheduling, Comlink RPC patterns, module workers, and performance profiling strategies.
Master the OffscreenCanvas API to offload rendering from the main thread. Covers worker-based 2D and WebGL rendering, animation loops inside workers, bitmap transfer, double buffering, chart rendering pipelines, image processing, and performance measurement strategies.
