What are the best practices for creating objects in JavaScript?

When creating objects in JavaScript, it's best to use object literals for simple structures, and constructor functions or classes for more complex ones.

Can you explain the difference between object literals and constructor functions?

Sure! Object literals are a quick way to create objects using curly braces, while constructor functions allow you to create multiple instances of an object with the 'new' keyword.

What about using classes? Are they better than constructor functions?

Classes in JavaScript provide a clearer syntax and are syntactic sugar over constructor functions, making inheritance and object-oriented programming easier.

Are there any performance considerations I should be aware of?

Yes, while the performance difference is often negligible, using object literals can be faster for single instances, while classes are better for multiple instances due to their prototype chain.
