使用.includes对数组执行.filter操作的方法是首先使用.includes方法来判断数组中的每个元素是否包含指定的值,然后使用.filter方法来过滤出符合条件的元素。 .includes方法是JavaScript中数组的方法之一,它用于判断数组中是否包含指定的值。它返回一个布尔值,如果数组中包含该值,则返回true,否则返回false。
react可以通过高阶组件(HOC)来扩展,而Vue需要通过mixins来扩展。 高阶组件就是高阶函数,而React的组件本身就是纯粹的函数,所以高阶函数对React来说易如反掌。相反Vue.js使用HTML模板创建视图组件,这时模板无法有效的编译,因此Vue不能采用HOC来实现。 6)构建工具 两者都有自己的构建工具: React ==> Create React...

To include files from another domain, you can add a whitelist of legal files and/or domains in the config function of your application: Example: varapp = angular.module('myApp', []) app.config(function($sceDelegateProvider){ $sceDelegateProvider...
ie11 react框架 对象不支持includes属性或方法 今天解决了一个IE11的兼容问题,关于attachEvent的。hEvent不是IE专有的么?是啊,这是IE专属呃,这么多年,不离不弃。IE的attachEvent不支持捕获阶段的事件处理程序,并且同一个处理程序能添加多次。非标准的IE专属,在IE11,彻底自己抛弃了...IE11不再任性,走上了标准...
The process includes contacting alpha olefin monomers with a catalyst system, which includes a catalyst and an activator (co-catalyst) in a reactant mixture. The catalyst is a transition metal catalyst, preferably titanium trichloride, and the co-catalyst may include an alkylaluminoxane, alone or...
The includes() method in React.js is used to determine if an element exists in an array. It returns a boolean value indicating whether the element is present or not. By default, it checks the entire array for the element's existence
