--- license: mit task_categories: - text-generation language: - en tags: - code - javascript size_categories: - 1M<n<10M --- **JavaScript-Code-Large** JavaScript-Code-Large is a large-scale corpus of JavaScript source code comprising around **5 million** JavaScript files. The dataset is designed to support research in large language model (LLM) pretraining, code intelligence, software engineering automation, and program analysis for the JavaScript ecosystem. By providing a high-volume, language-specific corpus, JavaScript-Code-Large enables systematic experimentation in JavaScript-focused model training, domain adaptation, and downstream code understanding tasks. JavaScript-Code-Large addresses the need for a dedicated JavaScript-only dataset at substantial scale, enabling focused research across frontend, backend, and full-stack JavaScript environments. . **1. Dataset Composition** Programming Language: JavaScript File Count: 5M+ JavaScript files File Format: .jsonl Content Types The dataset includes a wide variety of JavaScript constructs and paradigms, such as: - Functions (declarations, expressions, arrow functions) - Classes and prototypes - Modules (CommonJS and ES Modules) - Asynchronous patterns (async/await, Promises, callbacks) - Event-driven code - Closures and higher-order functions - Functional programming constructs - DOM manipulation code - Node.js backend logic - Frontend framework components - JSDoc comments - Error handling patterns - Modern ES6+ features **2. Intended Research Applications** 2.1 Pretraining - Training JavaScript code foundation models from scratch - Continued pretraining of existing LLMs - JavaScript-specialized language modeling - Tokenizer training for JS ecosystems 2.2 Fine-Tuning and Adaptation - Code completion systems - Intelligent IDE assistants - Automated refactoring tools - Conversational programming agents - JavaScript-specific copilots 2.3 Code Intelligence Tasks - Code summarization - Code-to-text generation - Documentation generation - Bug detection - Vulnerability detection - Clone detection - Code similarity modeling - Minified-to-readable code transformation - Static and structural analysis 2.4 Software Engineering Research - Empirical studies of JavaScript coding patterns - Analysis of async and event-driven architectures - Framework usage studies - Dependency modeling - AST-based experiments - Cross-version JavaScript evolution analysis **3. Relationship to [Java-Code-Large](https://huggingface.co/datasets/ajibawa-2023/Java-Code-Large)** JavaScript-Code-Large complements **Java-Code-Large**, enabling comparative research between: - Statically typed vs dynamically typed languages - Class-based vs prototype-based paradigms - Backend vs frontend dominant ecosystems - JVM vs Node.js environments Together, these datasets support cross-language transfer learning and controlled specialization studies. Thanks to open source community for all the guidance & support!!
