Can instanceof be used with interfaces?
An example of an AI chatbot conversation about using instanceof with interfaces in JavaScript.
Can instanceof be used with interfaces in JavaScript?
No, instanceof cannot be used directly with interfaces because interfaces are not actual objects in JavaScript.
So how can I check if an object implements an interface?
You can check if an object has the required methods or properties defined by the interface instead.
Can you give me an example of that?
Sure! You can use the 'in' operator or check for method existence, like this: 'if ('methodName' in obj) {...}'.
What about TypeScript? Does it handle interfaces differently?
Yes, TypeScript provides better support for interfaces, allowing you to use type checking at compile time.
