Mozilla Extending Javascript?

Nomad128 writes "Mozilla's Deer Park 1 Alpha RC appears to have extended the Javascript spec for the first time in quite some time. New features include Array object methods "every" (logical AND), "some" (logical OR), "map" (function mapping), and "forEach" (iteration). They also appear to have added native XML support. Will this speed up the development of AJAX applications and give Moz a leg-up over IE7?"

A signature I have seen somewhere

The march of progress:

C:
printf("%10.2f", x);

C++:
cout << setw(10) << setprecision(2) << showpoint << x;

Java:
java.text.NumberFormat formatter = java.text.NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
String s = formatter.format(x);
for (int i = s.length(); i < 10; i++)
System.out.print(' ');
System.out.print(s);

C++: #include printf("%10.2f", x); // or #include char s[14]; sprintf(s, "%10.2f", x); cout s; Java: String s = String.format("%10.2f", x); System.out.print(s);

Oh god did that ever come out wrong.

C++:
#include <cstdio>
printf("%10.2f", x);
// or
#include <cstring>
char s[14];
sprintf(s, "%10.2f", x);
cout << s;
Java:
String s = String.format("%10.2f", x);
System.out.print(s);
