TypeScript is an open source programming language developed by Microsoft and first released in 2012. It is designed to add type safety to JavaScript while conforming as closely as possible to the syntax and semantics of the ECMAScript standard.

It is a syntactical superset of the JavaScript programming language; all valid JavaScript source code is also valid TypeScript source code, but not vice-versa. TypeScript compiles (or transpiles) to JavaScript, meaning that it can be utilized to target any JavaScript environment. It can be used to develop JavaScript for both client-side and server-side applications.

问题描述
最近使用movable-view做了一个拖拽排序的功能,但是由于需要touchmove事件频繁setState来更新movable-view的坐标,导致Android的上的性能体验很差,IOS不会。

看了微信的文档,这种情况可以使用WXS来解决,请问Taro中能否使用WXS?如何使用呢?
