You can safely remove these lines as part of a build step (e.g. Processor it may cause to assertions to appear when unnecessary function names are stripped. These areĪutomatically removed from the included minified versions. Some of the files use console.assert() calls to catch bugs during development.

polyfill.js (minified: ) has everything in web.js plus es5.js and es6.js and es2016.js and es2017.js.Includes: html.js dom.js xhr.js cssom.js url.js fetch.js.web.js (minified: ) includes the most common Web polyfills - it assumes ES2015 support.Since I generally use several in my hobby projects, bundled/minified versions are available: So there is html.js for HTML, dom.js for DOM, etc. The polyfills are roughly split up into files matching 1:1 with Web standards (specifications, living standards documents, etc). Or just include scripts directly in your page via CDN (c/o RawGit): It is not packaged as Node.js module(s) there's nothing to require(), this is just for distribution.

You're already here! Great, just download it, or use: A more comprehensive list of polyfills can be found at The All-In-One Entirely-Not-Alphabetical No-Bullshit Guide to HTML5 Fallbacks by Paul Irish.
I use these in various pages on my sites most are by me, or I have at least tweaked them. There is no effort to produce 100% compliant behavior, or to completely hide differences in browser behavior.
#IE8 EMULATOR MAC CODE#
My philosophy is that it's better to write future-looking code that takes advantage of new Web platform APIs where possible, and fill in the gaps with polyfills. A few are experimental and called out as such, subject to change at any time. Most are for features shipping in major browsers. This is a collection of polyfills covering web platform features, from those defined as part of the ECMAScript standard to new web browser functionality.
