Ecmascript 5 and browsers
I was looking at browser usage statistics at http://www.w3schools.com/browsers/browsers_stats.asp and was completely shocked at the results.
I expected at least 50% of people still using IE8. I didn't realize that IE's market share is so low at 18%.
Does this mean if I want to create a public Website potentially available for 75% of the English Speaking population I can feel confident to use EcmaScript 5 features with some kind of EcmaScript 5 shim package as backup?
I found an EcmaScript5 package at https://github.com/kriskowal/es5-shim but the author doesn't make many promises:
"As closely as possible to ES5" is not very close. Many of these shims are intended only to allow code to be written to ES5 without causing run-time errors in older engines. In many cases, this means that these shims cause many ES5 methods to silently fail. Decide carefully whether this is what you want.

I wouldn't rely too much on W3Schools stats. They don't take a sampling from a wide variety of sites. Those stats are only for their site, and the demographic for a web dev site are the least likely to be using IE.

Actually, StatCounter shows similar results for IE8 (14.35% when you request the information by Browser Version, so it's reasonable to believe that your website will see numbers in that range.
