My question is : What's the difference between babel-preset-stage-0,babel-preset-stage-1,babel-preset-stage-2 and babel-preset-stage-3, and what's the best choice when we develop with ES6?

推荐答案

Babel的舞台预设等于 TC39流程以及每个提案可能会更改语言的不同状态.它们包括该阶段所有拟议变更的实现和polyfill.

Babel's stage presets equate to the TC39 Process and the different states of each proposal for a potential language change. They include implementations and polyfills for all of the proposed changes in that stage.

Stage-0中当前使用的是Strawman，不是 ES6.它是未来的Javascript，而且绝对不确定是否会将其纳入任何正式的ECMAScript规范中.

Anything currently in Stage-0 is Strawman, not ES6. It is future Javascript and absolutely not certain that it will ever make it into any official ECMAScript specification.

请不要仅将其设置为stage-0 ，这样它就可以在不了解其后果的情况下正常工作.

Please do not just set to stage-0 so it will work without understanding the consequences this will have.

仅包含ES6功能的Babel预设为 preset-es2015

The Babel Preset which contains only ES6 features is preset-es2015
