What are JavaScript object literals and how do I use them?

JavaScript object literals are a way to define objects using a simple syntax. You can create an object by enclosing key-value pairs in curly braces. For example: const person = { name: 'John', age: 30 };.

Can you give me an example of how to access properties in an object literal?

Sure! You can access properties using dot notation or bracket notation. For example, person.name will return 'John', and person['age'] will return 30.

What if I want to add a new property to the object?

You can add a new property by simply assigning a value to a new key. For example, person.city = 'New York'; will add a city property to the person object.

Are there any best practices for using object literals?

Yes! It's best to keep your object literals simple, use meaningful keys, and avoid nesting too deeply to maintain readability.
