Strings and comparison operators

By using comparison operators (==, !=, <, <=, >, >=), you can compare strings. Strings are compared in lexicographic order.

String comparison is case-sensitive, so lower case letters are always greater than upper case letters.

    <script type="text/javascript">
        var str1 = "Hello";
        var str2 = "hello";
        var str3 = "World";

        document.write("(str1 < str2): " + (str1 < str2) + "<br />");
        document.write("(str1 < str3): " + (str1 < str3) + "<br />");
        document.write("(str2 < str3): " + (str2 < str3) + "<br />");
    </script>
