This repository is a personal technical blog by the Chinese developer 'å´įžŊ' (yayujs), containing a large collection of in-depth JavaScript articles and accompanying demo code. The articles cover core JavaScript concepts such as prototype chains, scope, execution context, closures, 'this' binding, call/apply/bind, new, inheritance, and many utility implementations like debounce, throttle, deep copy, array flattening, currying, partial application, memoization, type detection, and object equality. The demos are standalone HTML/JS files that progressively build up implementations (e.g., 8 versions of a template engine, 7 versions of debounce), making them excellent educational resources. The repository also includes a small VuePress plugin for code copy functionality and examples of module systems (ES6, CommonJS, RequireJS, SeaJS). It is not a production application but a curated set of learning materials. The code is well-structured for teaching purposes, though it lacks modern tooling, automated tests, and CI/CD. Some examples use older JavaScript patterns (var, ES5) and outdated library copies (Underscore 1.8.3, RequireJS 2.3.5), but the core concepts remain relevant.
The LLM identified 4 files worth highlighting for reuse:
The final version of a template engine that compiles template strings into executable JavaScript functions. It demonstrates advanced string manipulation, regular expression parsing, and dynamic function creation using `new Function`. This component is self-contained and can be extracted as a lightweight template engine for any JavaScript project.
A complete debounce implementation with support for leading and trailing edge invocation, immediate cancellation, and proper context/argument handling. It is a standalone function that can be reused in any project requiring debounced event handling. The code is well-commented and demonstrates careful timer management and edge-case handling.
A Vue component that adds a 'copy' button to code blocks in VuePress documentation. It is a self-contained plugin with its own package.json and client root mixin. The component uses the Clipboard API and provides visual feedback. It can be extracted and reused in any VuePress project with minimal modification.
A polyfill for the ES6 Set object implemented using QUnit test-driven development. It demonstrates how to build a polyfill that passes a comprehensive test suite, covering edge cases like NaN handling, iteration, and method chaining. The code is self-contained and can serve as a reference for implementing other polyfills.
