What are the best practices for object iteration in programming?

When iterating over objects, it's important to use methods like Object.keys(), Object.values(), or Object.entries() for better performance and readability.

Can you explain the difference between these methods?

Sure! Object.keys() returns an array of a given object's own property names, Object.values() returns an array of the object's own property values, and Object.entries() returns an array of key-value pairs.

Which method is the most efficient?

Efficiency can depend on the use case, but generally, Object.keys() is often the fastest for just accessing keys, while Object.entries() is useful when you need both keys and values.

Are there any common pitfalls to avoid?

Yes, avoid using for...in loops without checking for hasOwnProperty, as it can iterate over inherited properties.
