Introduction to Coding

### Introduction to Coding

**Coding**, also known as **programming**, is the process of writing instructions for a computer to follow. These instructions, called **code**, allow the computer to perform specific tasks, such as running applications, displaying websites, or performing calculations.

Coding is the foundation of modern technology. Everything from video games to mobile apps, websites, and operating systems is powered by code.

### Basic Concepts in Coding

1. **Variables**: Containers for storing data values (e.g., numbers, text).
– Example: `let age = 25;`
2. **Data Types**: Specifies what kind of data a variable holds (e.g., integer, string).
– Example: `let name = “Alice”;` (String), `let age = 25;` (Number)
3. **Functions**: Blocks of code that can be reused and called to perform a specific task.
– Example: `function greet() { console.log(“Hello, World!”); }`
4. **Loops**: Allows you to repeat a set of instructions multiple times.
– Example: `for (let i = 0; i < 5; i++) { console.log(i); }`
5. **Conditional Statements**: Used to make decisions in your code based on certain conditions.
– Example: `if (age >= 18) { console.log(“Adult”); } else { console.log(“Minor”); }`
