2014 03 13 String Integers Comparison
"9" > "19" // true
"01" == "1" // false
If you have accidently forgotten to parse integers, or you have a blind sort function for attributes, you might face this problem.
In JavaScript's string comparison, it takes the first character's code. So, what is really happening equivalent to:
"9".charCodeAt(0) > "19".charCodeAt(0) // 57 > 49 --> true
"01".charCodeAt(0) == "1".charCodeAt(0) // 48 == 49 --> false
