Bun v1.1.25 boasts a benchmark of 1.29 million HTTP requests per second and adds node:cluster support, V8 C++ API bindings, a five‑fold S3 upload boost, standalone worker executables, Windows OMGJIT for WebAssembly, plus numerous Node.js compatibility fixes, all illustrated with code examples.
This article explains how to improve Android local‑search latency by embedding JavaScriptCore via JNI, detailing the performance bottlenecks, the integration workflow, essential JSC APIs, JNI usage patterns, and concrete C++/Java code examples that cut processing time by roughly half.
This article details Quark iOS's systematic stability effort in 2022, describing how the team identified top JavaScriptCore crashes, traced them to memory‑leak and AppWorker issues, applied targeted feature toggles, upgraded SDKs, and ultimately achieved a sharp drop in overall crash rates.
This article investigates a deadlock between the Main Thread and the JavaScriptCore Heap Collector Thread on iOS 13, explains the underlying mutex and RunLoop interactions, reproduces the issue with CFTimer‑based timers, and proposes an AutoReleasePool‑wrapped solution along with best‑practice recommendations for JavaScriptCore usage.
An in‑depth analysis reveals how a Main Thread and JavaScriptCore Heap Collector Thread can deadlock on iOS 13 due to RunLoop lock contention triggered by timer callbacks and AutoReleasePool memory reclamation, and provides a practical solution using scoped AutoReleasePool blocks to prevent the issue.
This article introduces NJCS, a lightweight dynamic deployment framework for iOS that enables rapid feature updates without App Store re‑approval, explains its background, integration steps, page creation, navigation APIs, UI component usage, notification handling, and provides practical code examples for developers.
Facing iOS App Store review delays, the article explores a lightweight approach that combines native iOS UI with JavaScript via JavaScriptCore, detailing JSContext and JSValue usage, code examples for UI components, and the conversion process that enables dynamic, low‑overhead UI updates without heavy frameworks.
The paper presents a custom JavaScript automatic binding tool for iQIYI’s React Node Desktop framework that parses C++ headers with libclang, applies user‑written YAML rules, generates multi‑inheritance‑aware wrappers via the Mate abstraction, and abstracts engine specifics through a Node‑Addon‑API‑based common layer to support both V8 and JavaScriptCore.
This article explains the role of JavaScriptCore in iOS development, covering its origins in WebKit, the internal architecture of JSCore—including lexer, parser, LLInt and JIT—its key features, and how developers can use JSContext, JSValue, and JSExport to bridge Objective‑C and JavaScript for hybrid applications.
JavaScriptCore, the iOS‑embedded JavaScript engine derived from Safari’s WebKit, offers a lexer, parser, interpreter and optional JIT, exposing APIs such as JSContext, JSValue and JSExport so Objective‑C/Swift code can evaluate scripts, exchange data, and interact bidirectionally, enabling lightweight hybrid app development with automatic tracing garbage collection.
Learn how to unlock JavaScriptCore's hidden debugger on iOS by locating the framework version, building the source with private headers, creating a custom Debugger subclass, and integrating it into an Xcode project, complete with code examples and configuration tips.
This article explores how to improve the legacy UIWebView on iOS by using the lightweight KakiWebView component, discussing motivations for WebView adoption, JS‑Native interaction via JSBridge and JavaScriptCore, code organization strategies, and a set of extensible plugins.
This article explores how JavaScript has become integral to client‑side development, introduces the JavaScriptCore framework that enables iOS apps to execute JavaScript, and provides detailed guidance on its architecture, core classes, concurrency model, object bridging, memory management, and error handling.
This article explains how JSPatch leverages JavaScriptCore to let iOS developers dynamically update UI layouts and fix bugs by writing JavaScript that calls Objective‑C APIs, compares it with other hot‑update solutions, and offers practical usage guidelines.
JSPatch is an open‑source iOS dynamic‑update framework that leverages Objective‑C runtime and JavaScriptCore to let developers call and replace native methods via JavaScript, with detailed explanations of its core principles, method invocation, replacement, struct and C‑function support, and advanced implementation tricks.
