Type Annotations, a language feature available in many modern programming languages, provide a way to specify information about the types of data that can be stored in variables, passed to functions, and returned from functions. This extra information can be used by the compiler or interpreter to perform typechecking and ensure that the program is well-typed. Typechecking can help to prevent errors and make code more robust and reliable.
Benefits of Type Annotations
There are several benefits to using type annotations in your code:
