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.
