It would've been nice to have an 'I don't care, proceed anyway' button. The check excludes Safari 7, which runs the demo just as well as Chrome.

^ removes the hasWebGLSupport() invocation.

Very nice demo, though!

It was in 1997. Apple wasn't doing so well at the time.

Take another look at the last sentence. :P

    NSString *pattern = @"\\d", *string = @"੧";
    NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:pattern
                                                                           options:NSRegularExpressionCaseInsensitive
                                                                             error:nil];

    NSUInteger numMatches = [regex numberOfMatchesInString:string
                                                   options:0
                                                     range:NSMakeRange(0, [string length])];

    numMatches ? NSLog(@"%@ found by %@", string, pattern) : NSLog(@"%@ not found", string);

I find random differences far too often.

FTFY :)

In other words: there was a WebObjects after v4? ;-)

> swizzling happens only once at compile time.

Objective-C is a dynamic language in every sense of the term.

As examples, at runtime, you can:

- change an existing class' superclass - swizzle methods - create a class ex nihilo (though it'd be a better idea to inherit from NSObject) - give that class (or even an existing one) methods, ivars, and properties

.. and much more

Visit the runtime reference[1] and jump into a running Objective-C app with GDB or F-Script. It's a lot of fun.
