object array syntax

[aliensite]

Can I have an array of objects without numbering?
I have an array I frequently edit, and its a pain
to renumber the entire array if I insert an object
in between existing objects.

// define object with constructor function
function car(make, owner) {
this.make = make
this.owner = owner
}
// array object constructor
mycar = new Array()
mycar[0] = new car("Ford", "Ken")
mycar[1] = new car("Chevy", "Tom")
mycar[2] = new car("Dodge", "Jerry")

Use an array literal:

var myObjects = [ new Object(...),
new Object(...),
new Object(...) ];

Use an ArrayList. It is in the java.util package.

Try:
mycar = [];
mycar.push(new car("Ford", "Ken"));
mycar.push(new car("Chevy", "Tom"));
mycar.push(new car("Dodge", "Jerry"));

Don't you mean

num = 0;
mycar[num++] = ...;

or

num = -1;
mycar[++num] = ...;

?
