HarmonyOS Development: What are ArkTs?

ArkTS is the main language for HarmonyOS application development, designed to build high-performance applications. It is a language that has been optimized and expanded based on TypeScript syntax, making it easy for developers familiar with TypeScript to learn. ArkTS is preferred for application development due to its performance, underlying interaction, complexity, development efficiency, and future development trend. The declarative development paradigm is the future of development, with advantages including code simplicity and readability, high-level abstraction, performance optimization, and portability. ArkTS has several advantages, including high development efficiency, superior performance, and an ecology that is easy to advance quickly. The ArkTS architecture consists of a declarative UI front-end, language runtime, declarative UI backend engine, rendering engine, and platform adaptation layer. ArkTS enforces static typing, prohibits changing object layout at runtime, restricts operator semantics, and does not support structural typing. The language extends capabilities such as basic syntax, state management, and rendering control. ArkTS is the official way to push for application development, and it is recommended that developers start with ArkTS directly. Overall, ArkTS provides a high-performance and efficient development experience for HarmonyOS application development.
