## What it is
A Chinese translation of the 'How JavaScript Works' tutorial series explaining JavaScript internals such as the event loop, V8 engine, memory management, service workers, and WebAssembly. It is a curated educational document collection rather than runnable software.

## Use cases
- learn how the javascript event loop works
- understand v8 engine internals and optimization tips
- study javascript memory management and leaks
- learn how service workers and web workers function
- understand webassembly vs javascript use cases
- learn javascript security topics like xss and csrf
- study javascript design patterns and functional programming

## When to choose
- you want a structured deep-dive into JavaScript runtime internals in Chinese
- you are preparing for frontend interviews covering event loop, memory, and rendering
- you want explanations of browser APIs like service workers, WebRTC, and Shadow DOM

## When to avoid
- you need runnable code, libraries, or tools rather than tutorials
- you need up-to-date coverage of the latest JavaScript features
- you prefer English-language original content (use the SessionStack blog directly)
