Maybe I didn't word that correctly. It was created as a set of babel plugins but because like you said users shouldn't know what a babel preset is we have the cli tool which acts the same as babel-cli so you don't need to do

The way the minifier is currently implemented is just as a babel preset. We figured users would want to use the tool standalone without babel and the simpliest thing we thought of was to wraps babel-cli and pass in the preset. https:/

I would like that too! I don't think there have been any features added since the last one with Babel 6 release. Yeah there's multiple JavaScript parsers: esprima, acorn, shift, babylon (uglify has their own parser I think). There

Yeah, the transformation itself shouldn't be bad. Made a Babel transform real quick for this particular example: http://astexplorer.net/#/ZT6HYai08w

If you don't want to use regenerator and your environment supports generators already you can use the async-to-generator transform https://gist.github.com/rauchg/8199de60db48026a6670620a1c33b...

Yep, it's our plan to do something like that with community help - have a PR open for discussion at https://github.com/babel/babel/pull/3476 . Also https://twitter.com/samccone/status

You can use the env option to change the transforms per env http://babeljs.io/docs/usage/babelrc/#env-option

As others have mentioned there are node and browser specific presets you can use. Also opened a PR for discussion about adding an environment award preset in babel or supporting it in core at https://github.com/babel/ba

Haha sorry the code itself is a joke right - I just mean the setup in the package.json (I posted it above) FYI: in reference to https://twitter.com/rauchg/status/712799807073419264

I left a comment on the site - but try https://gist.github.com/rauchg/5b032c2c2166e4e36713#file-pac... npm i -D babel-cli babel-preset-es2015 babel-preset-stage-0 babel-plugin-transform-runtime echo "export defaul

Yeah I think we can try adding something like that to the homepage. npm install --save-dev babel-cli babel-preset-es2015 echo '{ "presets": ["es2015"] }' > .babelrc echo "console.log(`1 + 1 = ${1 + 1}`)

If we don't decide to include "everything" by default, we can work on better docs (help is appreciated in where that could be improved as well as contributors!), and create a better setup experience with something like a `bab
