What are some real-world examples of array methods in JavaScript?

Array methods like map, filter, and reduce are commonly used in JavaScript for data manipulation. For instance, you can use map to transform an array of user objects into an array of user names.

Can you give me a specific example using the filter method?

Sure! If you have an array of products, you can use filter to get only the products that are in stock. For example: const inStockProducts = products.filter(product => product.stock > 0);.

What about the reduce method? How is it used?

The reduce method is great for aggregating data. For example, you can sum up the total price of items in a shopping cart: const totalPrice = cart.reduce((total, item) => total + item.price, 0);.

Are there any other array methods that are useful?

Yes, methods like forEach for iteration, some for checking conditions, and find for locating specific items are also very useful!
