Deno’s founder Ryan Dahl reveals that swapping the long‑used V8 engine for QuickJS reduces the size of a compiled Hello‑World binary from about 65 MiB to roughly 35.6 MiB—a 45 % reduction—while introducing an experimental engine option that brings new trade‑offs in compatibility, performance, and cross‑platform support.
The article chronicles French programmer Fabrice Bellard’s extraordinary career, highlighting his groundbreaking C projects—from the LZEXE compressor and the Harissa JVM to FFmpeg, QEMU, TinyCC, QuickJS, and a record‑breaking Pi calculation—showcasing how a single developer reshaped multiple domains of software engineering.
This article explores how the new QuickJS engine enables full‑featured ES2023 JavaScript within Nginx using the njs module, allowing developers to write modern async code, import/export modules, and implement complex routing and security logic directly in the web server configuration.
QuickJS manages memory using reference counting for each object combined with a cycle‑collector that periodically scans roots, decrements child references, and frees objects whose counts drop to zero, while also supporting traditional reachability‑based garbage‑collection techniques such as mark‑sweep, copying, and generational collection.
This article provides a comprehensive technical overview of JavaScript language standards, the architecture and optimization techniques of major JavaScript engines such as V8 and TurboFan, introduces the lightweight QuickJS engine with its features, file layout and memory management, and demonstrates how to embed QuickJS with libuv for asynchronous I/O using detailed C code examples.
This article explores the design and implementation of a portable, high‑performance JavaScript engine, covering ECMAScript basics, V8 TurboFan optimization, the QuickJS engine architecture, memory management, building and extending QuickJS, and integrating it with libuv for asynchronous I/O.
An in‑depth technical overview describes how a WebAssembly‑plus‑QuickJS sandbox architecture enhances web security, improves developer experience, and delivers benchmarked performance gains for next‑generation open web applications, while maintaining compatibility with W3C standards and integrating with existing e‑commerce platforms.
This paper proposes a WebAssembly‑QuickJS sandbox that isolates JavaScript execution and uses Shadow DOM/iframe for CSS isolation, delivering W3C‑compliant, high‑performance security for web apps, achieving 355× communication gains over mini‑programs while maintaining a lightweight, extensible ecosystem for e‑commerce plugins.
This article explains the design of a WebAssembly‑based security sandbox using QuickJS, detailing its background, goals, technical architecture, performance benchmarks, and future roadmap for building a safer, standards‑compliant open web ecosystem.
This article explains the Cube mini‑program rendering stack, its modular architecture, thread model, advanced Flow Layout and Inline Text support, CSS stylesheet capabilities, QuickJS integration, multi‑mode packaging and performance benchmarks, showing how it achieves fast startup, low memory usage and near‑native experience on low‑end devices.
This article investigates why JavaScript's Object.keys() may return keys in an unexpected order, explains the specification‑defined sorting rules for integer and string properties, demonstrates the issue with timestamp tags on iOS and Android, and explores the actual implementations in QuickJS and V8 engines.
