This repository is a Russian translation of the 'You Don't Know JS' book series by Kyle Simpson. It consists entirely of Markdown files organized by book volume (e.g., 'up & going', 'scope & closures', 'this & object prototypes', 'types & grammar', 'async & performance', 'es6 & beyond'), each containing chapters, forewords, appendices, and tables of contents. The content is educational, teaching JavaScript language mechanics, async patterns, ES6 features, and more. It is not a software application, library, or data pipeline; it is a static documentation/translation project. The translation is community-driven and may contain partial or inconsistent translations. The technical content is based on ES6 and earlier specifications, making some sections outdated (e.g., references to asm.js, SIMD, Object.observe). No runnable code, tests, or build tooling are present.
