Is it possible to perform type casting between different data types in Go?

In the Go language, type casting is possible, but it is strict and safe. Casting is possible between compatible types, such as between numeric types (int, float64, etc.), or between types with the same structure (for example, user-defined types based on basic types). You cannot simply cast, for example, a string to a number without explicit conversion.

Example of casting numeric types:

var a int = 42
var b float64 = float64(a) // explicit cast from int to float64

You can also cast interfaces to specific types using type assertion:

var i interface{} = "hello"
str, ok := i.(string)
if ok {
    fmt.Println(str)
}

Thus, type casting in Go requires explicit indication and only works for compatible types.
