Who Is This For?

These pages are for anyone who wants to understand programming in a simple way.

• Beginners: If you've never written code before, this will help you get started.
• Learners: If you already know some programming but need a quick reminder, these pages will refresh your knowledge.

Programming concepts are the same in all languages; they just look different. For example:

Example in Python:

print("Hello, World!")

Example in JavaScript:

console.log("Hello, World!");

Both codes do the same thing—print "Hello, World!"—but they are written differently.

Next, let’s learn how to start programming! 

Get Started with Programming

To become good at programming, you first need to learn the basic concepts.

No matter which programming language you choose, the core ideas remain the same.

5 Core Concepts to Learn First:

1. Variables – Store information.
2. If Statements – Make decisions in code.
3. Arrays – Hold multiple values.
4. Loops – Repeat actions automatically.
5. Functions – Organize code into reusable blocks.

It's best to learn them in this order. You also need a basic understanding of:

• Data types (numbers, text, etc.)
• Boolean logic (true/false conditions)
• Operators (math and comparison symbols)

Once you understand these, you can move on to advanced topics.

Programming Languages

A programming language is how we tell a computer what to do using special keywords.

Different languages are used for different tasks:

• JavaScript → Web development
• Python → Artificial intelligence
• C/C++ → Microcontrollers and system programming

Each language has its own syntax (the way code is written).

Here’s how a countdown from 10 is written in different languages:

Python:

for i in range(10, 0, -1):
    print(i)
print("Liftoff!")

JavaScript:

for (let i = 10; i > 0; i--) {
  console.log(i);
}
console.log("Liftoff!");

The logic is the same, but the way you write it is different.

Start Programming!

If you're new to coding, try these concepts in Python or JavaScript first. Since programming concepts stay the same across languages, you can easily switch to another language later.

What is a Variable?

A variable is like a container that stores information. It has a name, and inside it, we can store a value.

For example, imagine a box labeled favFruit, and inside the box, we put "apple".

Example in Python:

favFruit = "apple"

Here:

• favFruit is the name of the variable.
• "apple" is the value stored inside it.
• = assigns the value to the variable.

We use variables to store and reuse information in our code.

Creating a Variable in Different Languages

Let’s create a variable called favAnimal and store "turtle" in it:

Python:

favAnimal = "turtle"

JavaScript:

let favAnimal = "turtle";

Java:

String favAnimal = "turtle";

C++:

std::string favAnimal = "turtle";

No matter the language, the concept stays the same!
