I was answering to a parent who seems to have deleted his comment.
I'm not suggesting that everybody should know everything about their trade. Polyfill on the other hand is an extremely common thing in the trade. You'd expect a surgeon to know what a scalpel is.
Plus, he put it like: "I don't know what it is and I don't care". How about bothering to Google the names you don't know, instead of demanding everybody else to include introductory terminology lessons in their posts?
