> How big is the "full" set of polyfills anyway? Google's polyfills for custom elements that they ship with Polymer weigh in at around ~151Kb of JavaScript, around 10x the size of a small library like Underscore, and 4-5x times the size of an MVC framework like Angular. And they only cover about 5-6 specs (the 4 webcomponent specs and a few more to support them) Those are admittedly hard to polyfill features that will be bigger than most, but it turns out that polyfilling "everything" is hard and would add significant page weight. |
