Without wanting to mangle too much
But the language already provide a sort function for arrays
that you could reuse
also the valueOf() method of the Date object could
simplify a lot the comparison of values
list = [ new Date( 1901, 1, 1), new Date(), new Date(2003,1,5), new
Date(2005,3,5) ];
function sortDateArray2( a, b )
{
a = a.valueOf();
b = b.valueOf();
if( a > b )
{
return 1;
}
else if( a == b )
{
return 0
}
return -1;
}
list.sort( sortDateArray2 );
trace( list.join( "\n" ) );
