Failed to minify the code

[alexpanchuk]

Hi =) Got the error, when building my project, using create-react-app

Failed to minify the code from this file: ./node_modules/ical-generator/src/_tools.js:10 

Here they sad, that is because you

don't compile their code to ES5 before publishing to npm

Thank you!)
