我遇到了以下行为:
> foo = {};
{}
> foo.bar = function bar() { return arguments; }
[Function: bar]
> bar()

在转除此代码后,该代码无法工作
import React from 'react';
import ReactDOM from 'react-dom';
import firstLow from './moniesApp.js';
ReactDOM.render(<firstLow />, document.getElementById('content'));
but this does
import React from 'react';
import ReactDOM from 'r
我的量角器几天前还在运行,那时我开始遇到:

我开始业力在安古拉杰尤曼脚手架。错误“无法调用未定义的方法‘模块’”在gruntfile.js中,由约曼在第一行module.exports = function (grunt) { ...上生成
karma.conf.js是
module.exports = function(config) {
config.set({
// base path, that will be used to resolve files and exclude
basePath: '',
frameworks: ['jasmine'],
// list of files
我遇到了一个出口场景的小问题,我不知道为什么。我可能需要一个Babel插件来解决它,但不确定是哪个。
// a.js
export function fromA() {}
// b.js
export function fromB() {}
// index.js
import * as a from './a'
import * as b from './b'
export default { ...a, ...b}
// test.js
import all from './index'
const { fromA } = all
我有这样的东西:
//ActionTypes.js
export const a = 'a';
//Reducer.js
import a from './ActionTypes';
//export reducer function that uses string a
//Actions.js
import a from './ActionTypes';
return {type: a, data: 'something'}
但在reducer.js和actions.js中,'a‘都是未定义的。据我所知,没有循环依
