🆚 Fastly Polyfill vs. jQuery

Fastly Polyfill is a service that reads the User-Agent header of each request and returns polyfills appropriate for the requesting browser.

jQuery is a fast, small, feature-rich JavaScript library designed to simplify HTML DOM tree traversal and manipulation, event handling, CSS animations, and Ajax.

It provides a cross-browser selector engine, formerly known as Sizzle, supports deferred and promise objects for asynchronous workflows, has built-in JSON parsing and utility functions, and allows extensibility through a large ecosystem of plugins.
