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

Go has a static typing system, which means that the type of a variable is determined at compile-time and cannot be changed at runtime. This is in contrast to a dynamic typing system, where the type of a variable is determined at runtime based on the value assigned to it.

In a static typing system like Go, the compiler checks that the types of variables, functions, and expressions are consistent before the program is executed. This helps catch type-related errors early in the development process, before the code is actually run.

On the other hand, a dynamic typing system like Python or JavaScript allows for more flexibility in programming, as variables can change types at runtime. However, this also means that type-related errors may not be caught until the code is actually executed, which can lead to harder-to-debug runtime errors.
