NativeScript then uses the abstractions described in the XML files to call native UI elements of each platform. Application logic developed in Angular and TypeScript can be developed independent of the target platform as well. A NativeScript mobile application is built using the node.js runtime and tooling.

JavaScript-based web application frameworks, such as React and Vue, provide extensive capabilities but come with associated trade-offs. These frameworks often extend or enhance features available through native web technologies, such as routing, component-based development, and state management.
JSON being a subset of JavaScript can lead to the misconception that it is safe to pass JSON texts to the JavaScript eval() function. This is not safe, due to certain valid JSON texts, specifically those containing U+2028 LINE SEPARATOR or U+2029 PARAGRAPH SEPARATOR , not being valid JavaScript code until JavaScript specifications were updated ...
Douglas Crockford originally wrote json2.js as an API for reading and writing his (then up-and-coming) JSON data format. It became so widely used that browser vendors decided to implement its API natively and turn it into a de facto standard ; Since json2.js now implements features native to newer browsers into older browsers, it has become a ...
React components wrap existing native code and interact with native APIs via React's declarative UI paradigm and JavaScript. [23] TypeScript is often used over JavaScript in modern React Native applications due to its increased type safety. [24] While React Native styling has a similar syntax to CSS, it does not use HTML or CSS.
CL-JavaScript: Can compile JavaScript to machine language on Common Lisp implementations that compile to machine language. [11] BESEN: A complete JIT-compiling implementation of ECMAScript Fifth Edition written in Object Pascal. [12] Hermes: developed by Facebook for React Native mobile apps [13] Can also be used independent from React Native.
TurboFan compiles this bytecode into machine code. In other words, V8 compiles ECMAScript directly to native machine code using just-in-time compilation before executing it. [ 18 ] The compiled code is additionally optimized (and re-optimized) dynamically at runtime, based on heuristics of the code's execution profile.
XMLHttpRequest (XHR) is an API in the form of a JavaScript object whose methods transmit HTTP requests from a web browser to a web server. [1] The methods allow a browser-based application to send requests to the server after page loading is complete, and receive information back. [ 2 ]
