ios - How does the Swift string more than operator work -

this question has answer here:

• what mean string , character comparisons in swift not locale-sensitive? 3 answers

i don't have experience swift , come php / python / javascript background, please bare me.

i reading documentation on swift programming language, when came across the following code snippet:

let names = ["chris", "alex", "ewa", "barry", "daniella"]  func backwards(s1: string, _ s2: string) -> bool {    return s1 > s2 }  names.sort(backwards) // ["ewa", "daniella", "chris", "barry", "alex"] 

what don't seem able find, how > operator works in context, thought count amount of characters , return boolean based on that, logic following snippet should return false:

"cd" > "abc" // true 

could please explain going on here? thank you.

i believe javascript uses same string comparison approach, , same syntax. in javascript use localecompare(). , in swift alternatively use localizedcompare(_:) (or 1 of other string comparison functions). they're different ways, , different options, alphabetically compare strings.
