On build: 'error TS2304: Cannot find name 'Set'.'

[Talamantez]

I ran into this error when running 'yarn build.' Adding "es6" to the "lib" section of tsconfig.js after pulling up this solution to the error on stackoverflow: https://stackoverflow.com/questions/39416691/webpack-ts2304-cannot-find-name-map-set-promise

"lib": [
"dom",
"es5",
"es6", <----- Added this
"es2015.promise"
]

That's odd. I haven't seen any issues building with this as a dependency, though I also don't use yarn. Feel free to open a PR if you think this could help others.
