Example
The following example uses
var my_array:Array = new Array();
for (var i:Number = 0; i < 10; i++) {
my_array[i] = (i + 5) * 10;
}
trace(my_array); // output: 50,60,70,80,90,100,110,120,130,140
The following example uses
loop adds the numbers from 1 to 100.
var sum:Number = 0;
for (var i:Number = 1; i <= 100; i++) {
sum += i;
}
trace(sum); // output: 5050
The following example shows that curly braces ({}) are not necessary if only one statement
will execute:
var sum:Number = 0;
for (var i:Number = 1; i <= 100; i++)
sum += i;
trace(sum); // output: 5050
