NativeScript is an open source framework created by Telerik that makes native mobile app development easier for web developers. It enables developers to use JavaScript or TypeScript (with or without Angular or Vue) to build native mobile applications for iOS and Android. NativeScript apps render native UI components styled by a subset of CSS. Modules provide cross-platform native API abstractions. 100% of native APIs are available via JavaScript.
