The developer experience has long been given due attention by the React team and community. Examples include making sure React has clear error messages, emphasising components as a way to reason locally about app behaviour, designing APIs that are predictable and promote proper usage by design, etc. However, we haven't…
Thread safety is the avoidance of data races—situations in which data are set to either correct or incorrect values, depending upon the order in which multiple threads access and modify the data. When no sharing is intended, give each thread a private copy of the data. When sharing is important,…
An open-source JavaScript engine designed for React Native apps on Android is called Hermes. By turning on Hermes, many apps will start up faster, use less memory, and be smaller overall. Hermes is currently a React Native opt-in feature, and this tutorial shows you how to enable it.
The open source, WebAssembly and JavaScript V8 engine from Google was created in C++. Among other applications, it is used in Chrome and Node.js. It supports Windows 7 or later, macOS 10.12 or later, and Linux systems with x64, IA-32, ARM, or MIPS processors. It also implements ECMAScript and WebAssembly.…
You can add JavaScript support to any C or C compatible project by using the JavaScript engine ChakraCore, which has a C API. Linux, MacOS, and Windows all support compiling it for x64 processors. And only for Windows, x86 and ARM. Support for x86 and ARM processors on Linux and…
React Components with render implementations that reduce to other React Composite Components or React Host Components.
A React Native app may occasionally need to access a native platform API that is not by default available in JavaScript, such as the native APIs for using Apple or Google Pay. Perhaps you want to write some high-performance, multi-threaded code for things like image processing or reuse some existing…
