I'm facing a strange ES6 inheritance problem, where it seems I cannot call super() in my constructor. Here is my code: import BubbleTheme, { BubbleTooltip } from 'quill/themes/bubble' class LoopTheme extends BubbleTheme { constructor (quill, options) { super(quill, options) } extendToolbar (toolbar) { super.extendToolbar(toolbar) this.tooltip = new LoopTooltip(this.quill, this.options.bounds); this.tooltip.root.appendChild(toolbar.container); } } class LoopTooltip extends

I am not sure if this is a bug or something im doing wrong, i could not find much about it over google, so this is my last resource. Would i need to change something to my code to make it work ? This are my current specs: Webpack: 3.19.0 babel/core: 7.0.0-beta.34 babel-loader: 8.0.0-beta.0 Please refer to my packages.json if needed: http://paste.ubuntu.com/26187880/ I`m tryng to

用vue-cli做的项目，用了promise，结果IE下报promise未定义，甚至在比较老的andriod手机浏览器上会显示空白页面，解决方案如下： npm install babel-polyfill --save 在build目录下，webpack.base.conf.js里 entry: { 即可。 【说明】vue-cli项目里默认有babel转码器，但是： 举例来说，ES6 在Array对象上新增了Array.from方法。Babel 就不会转码这个方法。如果想让这个方法运行，必须使用babel-polyfill，为当前环境提供一个垫片。 原文：https://www.cnblogs.com/c2016c/p/9325162.html

官网： https://babeljs.io/docs/en 首先 npm init 初始化 npm install --save-dev babel-cli babel-preset-env 不知道为什么居然没成功下面这个 在package.json里面配置 ``` "build":"babel src -d lib" 在script里面配置执行脚本 "babel":{ "presets":["env"] } 编译环境 `` 最后就是执行命令 npm run build 文件放在src 目录下面，会生成lib目录 原文：https://www.cnblogs.com/cyany/p/9305300.html

vex使用...mapActions报错解决办法 vuex2增加了mapGetters和mapActions的方法，借助stage2的Object Rest Operator 所在通过 methods:{ } 酱紫去拿到action。但是我们需要安装babel-preset-stage-2的依赖。 可以使用babel插件， 该插件为 babel-plugin-transform-object-rest-spread 使用方法： npm install --save-dev babel-plugin-transform-object-rest-spread 新建 .babelrc 配置文件（切记不要忘记！！！） { "plugins": ["transform-object-rest-spread"] } 谢谢大家！！！ 原文：https://www.cnblogs.com/maqingyuan/p/9284916.html

大家知道，将ES6代码编译为ES5时，我们常用到Babel这个编译工具。大家参考一些网上的文章或者官方文档，里面常会建议大家在.babelrc中输入如下代码： { "presets": [ "es2015", "react", "stage-0" ], "plugins": [] } 我们现在来说明下这个配置文件是什么意思。首先，这个配置文件是针对babel 6的。Babel 6做了一系列模块化，不像Babel 5一样把所有的内容都加载。比如需要编译ES6，我们需要设置presets为"es2015"，也就是预先加载es6编译的相关模块，如果需要编译jsx，需要预先加载"react"这个模块。那问题来了，这个"stage-0"又代表什么呢？ 有了"react-0"，是否又有诸如"stage-1", "stage-2"等等呢？ 事实上， ”stage-0"是对ES7一些提案的支持，Babel通过插件的方式引入，让Babel可以编译ES7代码。当然由于ES7没有定下来，所以这些功能随时肯能被废弃掉的。现在我们来一一分析里面都有什么。 法力无边的stage-0 为什么说“stage-0” 法力无边呢，因为它包含stage-1, stage-2以及stage-3的所有功能，同时还另外支持如下两个功能插件： transform-do-expressions transform
