연관배열의 선언(making associative array of generic object)

It can be a good coding form to reference a Aarray type data and it also recduce your coding strokes. see below.

contacts = new Array();
contacts.push({first:"john", last:"Doe", age:26});
contacts.push({first:"Tom", last:"York", age:24});
trace(typeof(contacts[0].age));

Above example show as below on your output window.

number

With Loop, U can easily extract elements from array. see below.

contacts = new Array();
contacts.push({first:"john", last:"Doe", age:26});
contacts.push({first:"Tom", last:"York", age:24});
contacts.push({first:"Novak", last:"kim", age:60});
contacts.push({first:"Yoda", last:"", age:685});
for (i=0; i<contacts.length; i++) {
	trace("He is "+contacts[i].first+" "+contacts[i].last+". and He's "+contacts[i].age+" years old.");
}

and output is,

He is john Doe. and He's 26 years old.
He is Tom York. and He's 24 years old.
He is Novak kim. and He's 60 years old.
He is Yoda . and He's 685 years old.

Benefits of array,
1. the data for each person is known.(that is, U always need those three attributes)
2. Giving names to those three properties makes them easier to access(as opposed to memorizing the order).
