An example of an AI chatbot conversation about common mistakes with duck typing in programming.
What are common mistakes developers make with duck typing?
One common mistake is assuming that an object has a certain method just because it behaves like it. This can lead to runtime errors.
Can you give an example of that?
Sure! If you have a function that expects an object with a 'quack' method, but you pass an object without it, you'll get an error when you try to call 'quack'.
How can I avoid these mistakes?
You can use type checking or assertions to ensure that the object has the expected methods before calling them.
Are there any tools that can help with this?
Yes, tools like TypeScript can help by providing static type checking, which can catch these issues at compile time.
