Welcome to a new section of our course! So far, we have delved into Go's foundational elements. Now, we're going to focus on a crucial concept in Go: structs. Understanding structs will help you create more structured and readable code, making your programs easier to maintain.

In this section, you will learn:

• What structs are and why they are essential.
• How to define and use structs in Go.
• How to work with methods associated with structs.

Let's start with the basics. A struct is a composite data type in Go that groups variables together under a single name. These variables are called fields, and each field has a name and a type. Here’s an example:

In this example, Person is a struct that has three fields: FirstName, LastName, and Age. We also define a method FullName() that returns the person's full name.

Understanding structs is fundamental to building efficient and maintainable software. Structs allow you to model real-world entities more effectively. In our example above, modeling a person as a struct makes your code more readable and modular. You can easily create, access, and manage multiple Person instances without cluttering your codebase.

Knowledge of structs will also make it easier to understand more complex concepts like composition and design patterns, which we will cover later in this course. These advanced topics rely heavily on the proper use of structs.

Are you excited to practice these concepts? Let's dive in and start working with structs!
