Show the difference between storing strings as BSON and symbols.
require 'mongo'

bar = [:this, :that]
a = {:foo => ['this', 'that']}
b = {:foo => [:this, :that]}
bson_a = BSON.serialize(a).to_s
#=> "'\x00\x00\x00\x04foo\x00\x1D\x00\x00\x00\x020\x00\x05\x00\x00\x00this\x00\x021\x00\x05\x00\x00\x00that\x00\x00\x00"

Interesting differences in loops and incrementers
var i = 0, n = 100000000, t = 0;
console.time('i++');
for (; i < n; i++){
t += 1;

console.timeEnd('i++');
//i++: 147ms
i = 0; t = 0;
