What happens if I don't provide a default value?
An example of an AI chatbot conversation about default values in programming.
What happens if I don't provide a default value for a function parameter?
If you don't provide a default value, the parameter will be undefined if not passed when the function is called.
Can you give me an example of that?
Sure! If you have a function like function greet(name) { return 'Hello ' + name; } and call greet(), it will return 'Hello undefined'.
Is there a way to handle that situation?
Yes! You can set a default value like this: function greet(name = 'Guest') { return 'Hello ' + name; }. Now it will return 'Hello Guest' if no name is provided.
