Code to Modern Standards. Run Everywhere. poly.js 0.5 is out!

[unscriptable]

In case you haven't heard of poly.js ...

poly.js is a collection of tiny AMD modules that shim (aka "polyfill") old browsers to support modern (aka "ES5-ish") javascript.

So now you can write ES5-ish code like this and expect it to work in IE6:

normalizer = normalize.bind(null, config); // no more var that = this;
output = Object.keys(obj) // look! iterator functions on objects!
    .map(function (key) {
        return normalize(obj[key]).trim(); // it's about friggin time you got some trim, huh?
    })
    .filter(function (val) {
        return Date.parse(val); // simplified ISO8601 support (whatevs, man. it werks)
    });

Shims:

• Array -- forEach, map, filter, reduce, reduceRight, indexOf, lastIndexOf, isArray, etc.
  
• Date -- toISOString, parse (simplified ISO8601)
  
• Function -- bind
  
• JSON -- JSON2 spec: stringify, parse
  
• Object -- create, freeze, keys, seal, defineProperty, etc. (not all of these are fully functional. see README)
  
• String -- trim
  
• XHR -- full XHR 1.0 API
  

Size:

• 4.3KB gzipped, for everything, including full JSON2
  
• 3.1KB without JSON2
  
• 1.1KB for just the array and function shims (for instance, load whatever you want!)

Use it!  It's easy with curl.js:

curl(
    // use `preloads` to make sure shims are executed before app modules
    { preloads: ['poly/array', 'poly/function', 'poly/xhr'] },
    ['app/main']
);

Or just spread your ES5 love all over the place like this:

curl(
    // I plan to write me some serious ES5 shiz!
    { preloads: ['poly/all'] },
    ['app/main']
);
