How can I use spies in my project?

You can use spies to track function calls and their parameters without modifying the original function. This is useful for testing.

Can you give me an example of how to implement a spy?

Sure! If you're using Jasmine, you can create a spy like this: let mySpy = jasmine.createSpy('mySpy');.

What are the benefits of using spies in testing?

Spies help you verify that functions are called correctly, ensuring your code behaves as expected without altering its implementation.

Are there any limitations to using spies?

Yes, spies can only track calls to functions they wrap, so they won't work on functions that are not directly invoked.
