Struct Initialization

In Go, constructors for structs are typically just regular functions that return instances of the struct. Unlike some other programming languages, Go does not have special methods called "constructors." Instead, you can create functions with meaningful names that initialize and return instances of a struct.

It's common convention in Go to name such functions using the name of the struct with an initial capital letter. For example, if you have a struct named Logger, you might create a constructor function named NewLogger:

goCopy codepackage main

type Logger struct {
    // Fields of the Logger struct
}

// NewLogger is a constructor function for creating Logger instances.
func NewLogger() *Logger {
    return &Logger{}
}

func main() {
    // Create a Logger instance using the constructor function
    logger := NewLogger()
    
    // Use the logger...
}

In the code above, NewLogger is a constructor function that initializes a Logger instance and returns a pointer to it.

While it's a common practice to use constructor functions in Go, it's not a strict requirement. You can create instances of a struct directly without a constructor function if you prefer. However, constructor functions are often used to provide a consistent and clear way to create instances and encapsulate any initialization logic that may be needed.
