Notes for You:: Variables in ActionScript.

Variable:
is a named memory location, whose value may change during the execution of a program.

In order to grab a chunk of memory location and provide a meaningful name to it, we need to declare a variable or a constant.

Declaring a variable or a constant:
means allocating a memory location for some data.

In order to change the value in a variable or constant, we need to initialize or assign a value to it.

Initializing a variable or a constant:
means putting a data value in that allocated memory location.

Syntax for Declaration of a variable:
var nameOfVariable:datatype;

Note:
Default value of a variable or a constant, depends up on the type of a variable or constant.

Syntax for Declaration and Initialization of a variable:
var nameOfVariable:datatype = value;

Syntax for Declaration of multiple variables:
var nameOfVariable1:datatype, nameOfVariable2:datatype,...;

Syntax for Declaration and Initialization of multiple variables
var nameOfVariable1:datatype = value, nameOfVariable2:datatype = value,…;

Example Code:
var playerScore:int=10;
trace(playerScore);//10

var player1Health:int=100,player2Health:int=100;
trace("player1Health=",player1Health);//100
trace("player2Health=",player2Health);//100
