Why is one string greater than the other when comparing strings in JavaScript?

I see this code from a book:

var a = one;

var b = four;

a>b; // will return true

but it doesn't mention why one is bigger than four. I tried c = a and it is smaller than a and b. I want to know how JavaScript compares these strings.

Because, as in many programming languages, strings are compared lexicographically.

You can think of this as a fancier version of alphabetical ordering, the difference being that alphabetic ordering only covers the 26 characters a through z.

This answer is in response to a java question, but the logic is exactly the same. Another good one: String Compare "Logic".
