This repository is a comprehensive collection of JavaScript interview questions and answers, serving as an educational resource for developers preparing for technical interviews. It consists of hundreds of questions organized by topic and difficulty, each with detailed explanations, code examples, and further reading references. The content is structured with metadata enabling categorization, filtering, and multilingual support (English, Portuguese, Chinese). The repository includes automated systems for generating the README from structured data, validating content quality, and managing translations. As a public mirror of GreatFrontEnd's main repository, it provides a searchable, well-organized knowledge base covering core JavaScript concepts, web APIs, security, performance optimization, testing, and design patterns.
The Prompt Engineering Guide is a comprehensive, multilingual documentation site built with Next.js and Nextra that serves as an educational resource for prompt engineering with large language models. While the site itself is a web application, its core value lies in the extensive collection of tutorials, technique explanations, model-specific guides, and research summaries that constitute a structured knowledge base on effective LLM prompting. The repository includes interactive Jupyter notebooks that demonstrate practical applications of techniques like PAL, RAG, and ReAct, alongside hundreds of MDX pages covering topics from basic prompting to advanced agent building. Content is available in numerous languages, reflecting a commitment to global accessibility. The site features custom UI components for enhanced usability, such as announcement bars, course promotions, and copy-to-clipboard functionality, but these serve primarily to facilitate access to the educational content. Despite being actively maintained, the guide faces challenges typical of rapidly evolving fields: content requires frequent updates to keep pace with new LLM releases and research findings, and the multilingual nature increases the risk of translation drift. External links to papers, videos, and tools may also become stale over time. Nevertheless, the repository remains a valuable reference for practitioners and researchers seeking to understand and apply prompt engineering principles.
