wedgES

wedgES is a very lightweight attempt to bridge the gap between older JavaScript engines and modern ones based on kangax's es5 compatability table.

Since wedgES is a shim, it will not overwrite any functionality implemented natively.

To keep the wedgES as lightweight as possible, not all new ES5 methods have an associated polyfill, but only those deemed useful for development for older JavaScript engines.

WARNING!!!

This is an, as yet, untested framework, use at your own risk!

Inspiration/ Credits

The source – ./src – files contain comments giving credit to any code that was either used as inspiration, adapted and/ or lifted.

However, special mentions to:

• Kris Kowal's es5-shim: the main source for all the uber smarts in ./src/Object.js;
• Jed Schmidt's Gist: The Date.prototype.toISOString shim was lifted straight from here; and
• Mozilla Developer Network's JavaScript Reference: a plethora of knowledge, code examples and shims – for older JavaScript engines.
