What are some real-world examples of map, filter, and reduce?

Can you give me some real-world examples of how map, filter, and reduce are used?

Sure! Map, filter, and reduce are commonly used in programming for data manipulation. For example, in a shopping cart application, you might use map to apply a discount to each item, filter to remove out-of-stock items, and reduce to calculate the total price.

That makes sense! Can you provide another example?

Absolutely! In a social media app, you could use map to extract user names from a list of user objects, filter to find users who are active, and reduce to count how many active users there are.

What about in data analysis?

In data analysis, you might use map to transform raw data into a more usable format, filter to remove irrelevant data points, and reduce to summarize the data, like calculating the average.

These examples are really helpful, thanks!
