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

Question

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 t

Answer 1

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".
