Explain the use of Go's type aliases for creating new type names?

In Go, a type alias is a way to create a new name for an existing type. It does not create a new type, but rather provides an alternative name for an existing type, making the code more readable and expressive.
To create a type alias, you use the type keyword followed by the new name and the existing type. For example, if you want to create a new name for the int type, you could write:
type myInt int

This creates a new type name myInt that is an alias for the existing int type. You can now use myInt as if it were a new type:
var x myInt = 42

This creates a variable x of type myInt with the value 42.
Type aliases can also be used with struct types, array types, and other composite types. For example, you can create a type alias for a struct type:
type Point struct {
    X, Y int
}

type Pixel Point

This creates a new type name Pixel that is an alias for the existing Point struct type. You can now use Pixel as if it were a new type:
var p Pixel = Pixel{X: 10, Y: 20}

This creates a variable p of type Pixel with the values {10, 20}.
Type aliases can be useful for creating more descriptive names for types, or for providing compatibility with legacy code that uses different type names. However, it's important to note that type aliases do not create new types, and therefore do not provide any new behavior or functionality beyond what is already present in the existing type.
