Definitely a good point 👏🏻
Performance vs readability is a never-ending debate.
I intend how we can avoid two methods by just using reduce and explaining to the people how to use reduce syntactically!!
And yes, for loop is there to achieve all of these things.
You will get noticeable performance hit if your array has more than 1K elements. In worst case scenario you will iterate 2 times over 1K elements. Btw, what makes you think that reducer is not readable?
You can chain
map
andfilter
in functional languages, like for exampleF#
because there is no intermediate value.That's a good point with a great code presentation. 👍🏻
Thanks 🤗

Thank you for the kind words. 🙏🏻
It means a lot 🤗
Hi, thank you for this article ! I'm still learning and it helps to review basics. Just a little comment about the variables you use to illustrate the reduce fonction : in the code it's filterUser and in the article filterUsers, and the same goes with "user" and "users", I think it can be important for the understanding that the names remain consistent between the explanation and the code (well for me it's confusing when there's an extra or a missing "s" at the end sorry ahahah).
Ohh my bad 😅
I will make it clear in some time.
Thanks for your feeback.🙏🏻
Nice thumbnail!! 😂😂
haha, Thanks 😅
I would also like to know your feedback about this article.
I liked the .reduce() method explanation, personally I have only used it a few times, but still is hard for me to understand what it does. You explained it pretty well, thanks for sharing. 🤘
You're welcome 🤗
The map(), reduce() and filter() are array functions that transform the array according to the applied function and return the updated array obsession spell with cotton balls
Thanks
I am glad you like it. 🤗
Performing map, then filter is 2 iterations of the list. Despite some small readability gains, the performance loss is just too great.
The cover 🤣
Hope you also enjoyed the article 😅
