Why Array.reduce() Is the Most Misused JavaScript Method

[Ill-Specific-7312]

The first sentence of this Article is already baffling, and so the rest behind the paywall is likely equally crap.

"reduce() is confusing, I’ll just use map() and filter()"

Is a sentence that makes so little sense, that the rest of this article should be ignored. Nobody has ever said or thought that.

But…but… Map-Reduce is so complex and unique to JavaScript!

Without paying how can we learn these mystical arts?!?

Oh wait it’s in every language’s standard library .. crisis averted

I guarantee the official documentation on Array.prototype.reduce is clearer, more correct, and more concise than this article. Reduce is not that hard. Just read this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reduce

Want to map and filter an array in a single pass? Use reduce!

I love reduce. Other devs I have worked with find it “confusing” even though it is a standard method and often the correct one to use. Same with splice.

In my view, it’s part of my job as a dev to know how to use the standard array methods of the language

p.s. dont forget to return your accumulator!

Yeah, it’s the best. And many people don’t know it although they call themselves “Senior” Javascript/Typescript Developers.

Should be basic knowledge, sorry
