Objects

To create an object in JavaScript you can do:

var myobj = new Object();
myobj.prop = 1;

Using JSON you'd do:

var myobj = {prop:1};

Arrays

To create a new array you can do:

var a = new Array();
a[a.length] = 1;
a[a.length] = 2;

or using JSON:

var a = [1, 2];

Processing An Array by xinu on Apr 02, 2008 12:34 AM

In Perl you may have an array you'd like to iterate over. This would work:

for $line (@array) {
    print "line: $line\n";
}

Or you could use this abbreviated method with map():

print map ("line: $_\n") @array;
