If such a thing existed, languages could generate these artifacts and browsers could run them, without any JavaScript involved. This format would be easier for languages to support and could potentially exist in standard upstream compilers, runtimes, toolchains, and popular packages without the need for third-party distributions. In effect, we could go from a world where every language re-implements the web platform integration using JavaScript, to sharing a common one that is built directly into the browser.
提升代码可维护性和跨平台一致性，这样业务逻辑代码可以保持简洁统一，Android 和 iOS 主工程都不需要额外干预。
