Let me clarify the question first. When we talk about comparing two JavaScript objects for equality, considering nested properties, we are looking beyond a shallow comparison that only checks the first layer of properties. Instead, we delve into a deep comparison, where each property of the object is compared, including nested objects and arrays. This requires a recursive approach.
To illustrate, I will draft a function named deepEqual that takes two objects as parameters and recursively compares their properties for equality....
