Overview

<p>An overview to the main topics that we'll learn in this class. <a href="/course/coding-basics-1">Coding basics</a> covered everything about <a href="/courses/video/5/157/Using-Variables.html">variables</a>. Now it is time for us to move to <a href="/course/basics/operators">Operators</a>. Before we begin this course, I would suggest you take the <a href="/course/coding-basics-1">exam</a> questions for Coding Basics and score at least 80. In operators, we mostly deal with variables. In fact, we'll use variables every now and then through all the future courses. You should therefore have the basics down for all types of variables. After gaining command in coding basics (1 and 2), you can start this course without any hesitation.</p> <h2>Operators</h2> <p>When it comes to operators, we already know what an operator basically is. Before we proceed, we quickly go back to what we learned about them in the <a href="/course/coding-basics-2">previous course</a>. An operator can be used to perform operations on given data. For example, the ' ' operator is used to perform addition. We'll discuss <a href="/courses/video/7/198/Comparison-Between-Different-Types.html">various types</a> of operators and their uses later in this course.</p> <h2>Variables</h2> <p>You might wonder why <a href="/courses/video/5/157/Using-Variables.html">variables</a> are included in this course. As we discussed earlier, variables are the core part of Flash and are always associated with it. Here there is no need to go deeply into them; we'll just learn how various operations can be performed on different types of variables using operators. You can see every basic concept is repeated one way or the other in all the courses.</p> <h2>Nothing</h2> <p>Nothing can be referred to something that is empty. It's a new concept in this course and we'll have a clear discussion about it during the <a href="/courses/video/7/60/Null-vs-Undefined.html">actual video</a>. Smooth Operators is one of the most important topics in any programming language: try to learn it to the core and if you have any doubts, we are always there to help you through our community support.</p>

Overview

What are operators and why do we need them to create programs. We'll discuss various types of operators and their uses later in this course

01:49

Default Values

To understand operators, we first need to understand how variables work -- mainly when it comes to default values and why they differ for various variable types.

06:41

Equality

In this video we will compare between equality and assignment and learn how to work with both. We also differentiate between the assignment operator (=) and the equality operator (==)

06:40

Rational Operators

In this video we will see how to check if a variable is: bigger, smaller, greater or equals, smaller or equals and so on..... using rational operators

05:52

From Rational to Boolean

All the operators we worked with so far returned in our trace panel a value of true or false. In this video we'll see that connection of our operators results to the Boolean data type as we explore

05:26

Equality Operators

So far we've seen how to compare and see if values differ or match but we did not have a way to ask if not. In this sample we'll look into the equality operator(make it a bit more complex)

05:59

Comparison Between Different Types

In the heart of programming is the capability to compare between things. In this video we talk about comparing between different variable data types.

04:15

Explicit Equality

Sometimes knowing if something is equal just isn't enough and we need to know if it is explicitly equal and that's where explicit equality operator comes in...

08:05

Logical Operator

Logical operators enable us to compare a few things at a time such as AND, OR and NOT. We will learn the syntax to represent these operators using few examples

09:52

There Are Many Ways To Say No

doing exactly the oposite of the logical logic seams crazy but actually its a very great way to get things done. Let us learn how to say no in terms of programming

04:15

Null vs. Undefined

Why are there two ways of saying nothing? I ponder that as well as I try to explain their roles. In the process, we will learn the syntax and its application in code
