What are nested arrays and objects in programming?

Can you explain what nested arrays and objects are in programming?

Sure! Nested arrays and objects are data structures that contain other arrays or objects within them. For example, an array can hold multiple objects, and each object can have its own properties, including arrays.

Can you give me an example of a nested array?

Of course! Here's a simple example: let fruits = [['apple', 'banana'], ['orange', 'grape']]; This is an array containing two arrays, each with fruit names.

What about nested objects?

A nested object example would be: let person = { name: 'John', address: { city: 'New York', zip: '10001' } }; Here, the address property is itself an object.

How do you access elements in nested arrays and objects?

You can access them using indices for arrays and dot notation or bracket notation for objects. For example, fruits[0][1] gives you 'banana', and person.address.city gives you 'New York'.
