Loops are used to execute same statement of code for definite number of times.

There are three kinds of loops in ActionScript, the for loop, the while loop, and the do loop. There are also two other kinds that are loops used specifically for traversing a collection such as an Array, and can’t be used in any other way. These are the for…in loop and the for…each loop.

Logic is a part of our everyday lives – it’s a very familiar concept, therefore one of the easiest to understand. We are faced with questions all the time, with the “If” question being the most common. If I go to sleep early, I will be able to get up early. If I take this job, I will make more money. If I go to school, I will learn ActionScript. Using ActionScript, you can answer all of these questions using conditional statements.

Conditional statements allow you to setup the question or logic within your script, and if it is a true statement, then actions can be taken which are defined by you. Conditional statements create smarter scripts by performing an action based on something that has been setup in the program – it makes your scripts dynamic!

Similar to other languages, ActionScript offers designers and developers the use of the following conditional statements:

Remember any mathematical calculation we studied in our school,

Area = side * side (Formulae to find area of square)

Here side going to have some value, which we multiple and assign the final value in Area.
So each of the is a variable going to hold some number.

In programatic way of variable may have not only numbers, it may also have Text, Character, Boolean (True|False).

ActionScript comments are a way to keep your code clean and easy to read. Comments cannot be rendered because the browsers skip them. Most web designers are probably familiar with HTML comments, which are similar to ActionScriptcomments with the exception of the syntax.

Learn Actionscript Basics

There are two types of comments that you can use in ActionScript: single and multiple line comments. Single line comments are created using two slashes “//” in front of the line of text. Multiple line comment blocks are created by wrapping the text with a slash and an asterisk “/*” and closing the comment block by adding an asterisk and a slash “*/”. In CSS, comments are setup in a similar way with multiple line blocks.
