"2" > "12"

Question

Why it is true?
If checking number 2 > 12 false.

If checking length "2" > "12" false.

What's is checking?

Order? (Like "b" goes after "a" so b > a?).

Answer 2

Something didn't get so clear.

And if
"55" > "5"
codePoint(0) are the same.
But then one have 1 index and other no. So got null or \0 or something else?

Ps: I will code it to see, but for now I'm away from my computer. If you can help me.
