* 1、type为product、price或者sales,分别对应第1 ~ 3列 * 2、order为asc或者desc,asc表示升序,desc为降序 * 3、例如 sortData('price', 'asc') 表示按照price列从低到高排序 * 4、所有表格内容均为数字,每一列数字均不会重复 * 5、不要使用第三方插件 */ function sortData(type, order) { //完成...

如果使用过jQuery/ RxJS 时的“链式语法”,其实就可以算做 FP 中 monad 的实践;而近年来大多数前端开发者真正接触到 FP,一是从 ES6 中引入的 map / reduce 等几个函数式风格的 Array 实例方法,另一个就是从 React 中的函数式组件(FC - functional component)开始的。
