How does sinon.stub work?
sinon.stub is a function provided by Sinon.js library which creates a new function that can replace an existing function during tests, allowing you to control the behavior of the replaced function and assert how it is used. It can be used to stub out dependencies or API calls to isolate your code under test. When the stub function is called, it can be configured to return a specific value, throw an error, or call a separate function.
