Hmm. We have to target browsers waaaaaaaay older than that. Can bubleify guarantee to output code that IE11 understands?

@etpinard that is the best bubleify can do, it is targeted only for ES6 → ES5, not ES5 → ES3.

Hmm. Well that won't work then. plotly.js needs to be pure ES5.

@etpinard that is pure ES5, same as what we have now. target flag only indicates what new ES6 features are supported by target environment to avoid their handling, eg. some browsers have Object.assign or arrow functions, but do not do power a ** b etc, so since we indicate oldest target available in buble, we make sure we get pure ES5.

Could we put these config options in the package.json instead, so that all consumers bundling with browserify or webpack+ify-loader get the same results as us in our dist/?

Can the output bundle be minified by plain-old uglify-js? e.g. does

browserify -t bubleify src/plotly.js | uglify-js > bundle.js

work?

I'm not a big fan of this target option. I find it pretty confusing. Could we instead manually list all the transforms we want turned on?

chrome: 48,
firefox: 44,
edge: 12
},
transforms: {
arrow: true,
defaultParameter: false,
dangerousForOf: true,
},
sourceMap: false
},
