Question

I’m working out javascript cookbook by shelley powers. And in the book,

If two string literals only vary based on case, the uppercase characters are lexically
greater than the lowercase letter:

var sOne  = "Cat";
var sTwo  = "cat";
if (sOne >=  sTwo) // true, because 'C' is lexically greater than 'c'

but I cannot get the same result. this only works for me:

 var sOne = "Cat";
 var sTwo = "cat";
 if (sOne < sTwo) alert("whatever here"); 

Here it pops up a alert.I’m pretty confusion.Thanks guys!

The book is incorrect. It’s listed in the errata.
