Polyfills: everything you ever wanted to know, or maybe a bit less

Thank you so much! “My plan was to do static analysis of all the code in my app (at build time), and then create a tailored polyfill for only the features that I actually used. The idea being that there’s no point polyfilling Symbol and Map and Typed Arrays if I never use them.” — and that’s exactly what I tried to figure out myself: nobody should have to do any manual work in checking browser support and polyfilling used methods (a.k.a. safety net for new developers). And I did not come up with anything useful. I feel less dumb now. :)
