What are some real-world examples of using map, filter, and forEach in JavaScript?

Can you give me some real-world examples of using map, filter, and forEach in JavaScript?

Sure! The map method can be used to transform an array of user objects into an array of user names. For example, if you have an array of user objects, you can use map to create a new array containing just the names.

That sounds useful! What about filter?

The filter method is great for creating a new array with only the elements that meet certain criteria. For instance, if you have an array of products, you can use filter to get only the products that are in stock.

And how does forEach fit into this?

forEach is used to execute a function on each element of an array. For example, you could use forEach to log each user's name to the console without creating a new array.

Can you summarize when to use each of these methods?

Absolutely! Use map for transforming data, filter for selecting specific items, and forEach for executing side effects on each item.
