What is the difference between associative arrays and objects in JavaScript?

In JavaScript, associative arrays are actually just objects. Objects are key-value pairs, while arrays are ordered lists.

Can you give me an example of an associative array?

Sure! An associative array can be created using an object like this: let person = { name: 'John', age: 30 };.

How do I access values in an associative array?

You can access values using dot notation or bracket notation, like person.name or person['age'].

Are there any performance differences between using objects and arrays?

Generally, objects are faster for key-value lookups, while arrays are optimized for ordered data and iteration.
