What is the difference between Go's constant and dynamic typing?

Go is a statically-typed language, which means that the type of a variable is determined at compile time and cannot be changed at runtime. However, Go also supports a degree of dynamic typing through the use of interfaces and the empty interface type interface.

In Go, constants are always typed, which means that their type is determined at the time of declaration and cannot be changed later. For example, we can declare a constant of type **int** as follows:

const x int = 42

In contrast, dynamic typing allows for more flexibility in the type of a variable. In Go, we can use the empty interface type **interface{}** to define a variable that can hold values of any type. For example, we can declare a variable **x** of type **interface{}** as follows:

var x interface{} = 42

Here, **x** can hold a value of any type, including **int**, **string**, **bool**, or even custom types.

However, using dynamic typing can come with some trade-offs, such as reduced type safety and increased runtime overhead. In Go, we typically prefer to use static typing wherever possible to ensure that our code is safe and efficient.

In summary, Go is a statically-typed language, but also supports some degree of dynamic typing through the use of interfaces and the empty interface type **interface{}**. Constants in Go are always typed, and their type cannot be changed at runtime.
