What is the difference between an array and an object in JavaScript?

In JavaScript, an array is a list-like object used to store multiple values in a single variable, while an object is a collection of key-value pairs.

Can you give me an example of an array?

Sure! An example of an array is: let fruits = ['apple', 'banana', 'cherry']; This stores a list of fruit names.

And what about an object?

An example of an object is: let car = {make: 'Toyota', model: 'Camry', year: 2020}; This stores properties related to a car.

When should I use an array instead of an object?

Use an array when you need an ordered list of items, and use an object when you need to represent a collection of related data with key-value pairs.
