How do modern programming languages handle errors?

Modern programming languages use various techniques for error handling, such as exceptions, error codes, and assertions. For example, languages like Python and Java use exceptions to manage errors gracefully.

Can you explain the difference between exceptions and error codes?

Sure! Exceptions are objects that represent an error state and can be caught and handled, while error codes are simple values returned by functions to indicate success or failure. Exceptions provide more context and can propagate up the call stack.

What are some best practices for error handling?

Best practices include using exceptions for unexpected errors, validating inputs, logging errors for debugging, and ensuring that your program can recover gracefully from errors.

Are there any languages that do error handling better than others?

Languages like Rust and Go are often praised for their error handling mechanisms. Rust uses a Result type for explicit error handling, while Go uses multiple return values to indicate errors.
