[Giakko]

hello,
is there a way to create an array in this way?:

new Array('key1'='value1','key2'='value2','key3'='value3') ??????


thanks,

This type of construction would not be an array anymore (though some
call it an associative array). The preferred term in javascript is an
object.

{ key1: 'value1', key2: 'value2', key3: 'value3' }

JS doesn't know associative arrays. As Bart said - use an object instead.

What you created is an Object, and I am not sure that is what the OP was
asking about. It reads as if it is being asked for a shortcut method to
doing this:

var myArray = new Array()
myArray['key1'] = 'value1';
myArray['key2'] = 'value2';
myArray['key3'] = 'value3';

myArray is still an Array, it is just overkill when a plain Object would
suffice. Even then, it is still an "Object", just an extended Object
with Array properties.

Date is also an extended Object with extra properties. The moment any
programmers gets the *difference* between an Object and an Array is
the moment one stops perling/phping around and starts programming.
Don't tell me you didn't reach this state, please.

Date is a *built-in* object that only *inherits from* Object.prototype
through the prototype chain.

Array is the moment one stops perling/phping around and starts programming.

Google Groups knows that so far you never got any difference between
anything here (and the prospects for a change of that are equally bad),
so that point really is moot.

So is String, Number, Boolean or Array or so on. Listen: you learn the
basics of OOP or stop posting. It's getting annoying.

But `key1', `key2' and `key3' are _not_ properties that are *inherited* from
another (built-in) object, and newly created object is _not_ a *built-in*
object. That is the distinction you fail to make here.
