One thing I always really miss when working in other dynamic languages that aren’t JavaScript is the ability to access known (non dynamic) members of an associative array/object/hash (called a hash from here on out) through just a single dot. This matches C’s syntax of accessing struct members, as opposed to being forced into using array syntax which is harder to read IMO in languages like PHP and Perl. For example...

Creating a hash in:

JavaScript:	var Hash={foo:1, bar:2};
Perl:	my %Hash=(foo=>1, bar=>2);
PHP:	$Hash=Array('foo'=>1, 'bar'=>2);

Accessing a Hash’s member:

JavaScript:	Hash.foo or Hash['foo']
Perl:	$Hash{foo};
PHP:	$Hash['foo']

The reason this is preferable to me is it can make code like the following

Zones[Info['Zone']]['DateInfo'][Info['Date']]['UniqueEnters']+=Info['Count'];

much more readable by turning it into the following

Zones[Info.Zone].DateInfo[Info.Date].UniqueEnters+=Info.Count;
