When should I use default parameters in programming?

When should I use default parameters in programming?

Default parameters are useful when you want to provide a standard value for a function argument, making it optional.

Can you give me an example of a function with default parameters?

Sure! In Python, you can define a function like this: def greet(name, greeting='Hello'): return f'{greeting}, {name}!'.

What happens if I don't provide a value for the default parameter?

If you don't provide a value, the function will use the default value specified, in this case, 'Hello'.

Are there any downsides to using default parameters?

One downside is that it can lead to confusion if the default value is not well-documented or if it changes.
