How can I access nested data in a JSON object?

How can I access nested data in a JSON object?

You can access nested data in a JSON object using dot notation or bracket notation. For example, if you have an object like data = { user: { name: 'Alice', age: 25 } }, you can access the name with data.user.name.

What if the keys have spaces or special characters?

In that case, you should use bracket notation. For example, if you have data = { 'user name': 'Alice' }, you can access it with data['user name'].

Can you show me an example with an array?

Sure! If you have data = { users: [{ name: 'Alice' }, { name: 'Bob' }] }, you can access Bob's name with data.users[1].name.

What about using a loop to access all names?

You can use a loop like this: data.users.forEach(user => console.log(user.name)); This will print all the names in the array.
