The object to create.
name1,2,...N
The names of the properties.
value1,2,...N
The corresponding values for each

Description
Operator; creates a new object and initializes it with the specified
name
and
value
property pairs.
Using this operator is the same as using the
new Object
syntax and populating the property pairs
using the assignment operator. The prototype of the newly created object is generically named the
Object object.
This operator is also used to mark blocks of contiguous code associated with flow control
statements (
for
,
while
,
if
,
else
,
switch
) and functions.
For more information, see “Operator precedence and associativity” in Using ActionScript in Flash .
Example
The first line of the following code creates an empty object using the object initializer ({})
operator; the second line creates a new object using a constructor function:
var object:Object = {};
var object:Object = new Object();
The following example creates an object
account
and initializes the properties
name
,
address
,
city
,
state
,
zip
, and
balance
with accompanying values:
var account:Object = {name:"Macromedia, Inc.",
address:"600 Townsend Street",
city:"San Francisco",
state:"California",
zip:"94103",
balance:"1000"};
for (i in account) {
trace("account."+i+" = "+account[i]);
}
