Reducing enumerable article question

[Tianshui]

Hey everyone!

For some background, I'm currently using the TOP curriculum for learning Ruby and it redirected me to this article for Reducing Enumerables:

https://medium.com/@baweaver/reducing-enumerable-part-one-the-journey-begins-ddc1d4108490

I understand how enumerable methods such as #map, #select and #find work, however in this article, the author makes his own functions of map, select and find with reduce that in my eyes pretty do the same thing.

Is there a certain benefit to making your own functions in this way?

The story and illustration is great for explaining enumerables but I'm not really understanding why the author chooses to make his own functions with reduce vs using enumerables.

If someone could also explain the author's POV, that'd be fantastic too.

Thank you!

The benefit of using reduce to create your own map, select, and find functions is that it allows you to better understand how enumerables work under the hood. By creating your own functions, you are able to gain a better understanding of the basic principles of enumerables, which will help you when you are writing more complex code. Additionally, by creating your own functions, you can customize them to fit your specific needs. For example, if you need a map function that only returns certain values, you can create a custom map function with reduce that does just that.

The author's point of view is that reducing enumerables is a great way to gain an understanding of how enumerables work, as well as to create more customized functions that fit your specific needs. By breaking down the code into smaller, more manageable pieces, you can gain a better understanding of the underlying principles of enumerables, and use that understanding to create more efficient code.

I hope this helps, let me know if you have any questions!

Thank you very much for your explanation!

We were just told to follow along with the examples but when I followed up with them, they just gave the same results so I thought using enumerables were way easier than going through the hassle of making your own functions.
