在对象赋值解构Javascript中使用Colon

使用React.js和React Router

import React, { Component } from 'react';

const PrivateRoute = ({ component: Component, ...rest }) => (
  
)

*{ component: Component, ...rest }*

..rest是使用扩展语法但是做了*component: Component*什么

在ES6中,这将为此命名的新变量赋值 foo

let obj = {
  name: 'Some Name',
  age: '42',
  gender: 'coder'
};
let { name: foo, ...rest } = obj;
console.log({foo, rest}) // { foo: 'Some Name', rest: { age: 42, gender: 'coder' } }
//
