I was watching an Advanced Webpack video. Right at about the 10 minute mark he talks about detecting whether you need the Babel-Polyfill at runtime and then loading it if you need it. I found this very interesting. I conversed with him but twitter is to short of a format to answer my questions fully:
if (!feature) require("./polyBundle");
Was his recommendation which i full understand. My question is what feature/features do i need to look for? Do i need to include Modernizr? If i have to look for multiple features do i have to track Babel-Polyfill ever time i update it to see if i need to add/subtract features from the list?
