🎯 Our Mission
Deep JS is an interactive educational playground designed to demystify JavaScript internals through step-by-step visualizations.
Concepts like the Call Stack, Execution Contexts (GEC/FEC), Scope Chains, Closures, Prototype Chains, and the Event Loop are fundamental yet frequently abstract. Deep JS turns these invisible engine operations into tangible, animated step-by-step simulations based on ECMAScript specifications.
🚀 Core Highlights
- Spec-Compliant Simulation: AST-driven execution modeling adhering to ECMA-262 standards (Global Objects, Activation Objects, Heap pointers).
- Interactive Time Travel: Line-by-line stepping, auto-playback, and live inspection of memory allocations and scope resolution.
- Developer-First Design: Crisp dark-mode aesthetics, zero-layout-shift (CLS) ad integration, and frictionless usability.
- Full Bilingual Support: Seamless switching between English and Simplified Chinese.
💡 Sustainability
Deep JS remains free for developers worldwide. We sustain development and hosting via ethical, non-intrusive developer advertisements and voluntary community sponsorships.
