When should I use an array instead of an object in programming?

When should I use an array instead of an object in programming?

You should use an array when you need an ordered collection of items, and an object when you need key-value pairs.

Can you give me an example of when to use each?

Sure! Use an array for a list of names, like ['Alice', 'Bob'], and an object for user details, like {name: 'Alice', age: 25}.

What are the performance differences between arrays and objects?

Arrays are generally faster for indexed access, while objects are better for key-based lookups.

Are there any situations where one is preferred over the other?

Yes, if you need to maintain order and perform operations like sorting, use arrays. For structured data with unique keys, use objects.
