Solid Article! The only qualm I'll take is with #5 as it seems junior level devs already overuse `.map()`. `.forEach()` is a more analogous solution vs a `for loop`. Map, filter, and reduce have their applications and are really nice for, like you said, one lining code, but I feel map in particular is overused.

Thanks [D S](https://hashnode.com/@dstutts-dev).

I totally get your point here. In my opinion, in most cases it depends on your use case.

`map()` creates a new array populated with the results of calling a function on every element in the calling array whereas `forEach()` method executes a provided function once for each array element.

So Basically, if you want to obtain a modified form of the previous array, you can sure short go for `map()`, if you don’t want that, you use `forEach()`

[Apoorv Tyagi](https://hashnode.com/@apoorvtyagi) This is so true. I have infact explicitly written about it - [When not to use map](https://blog.niranjanborawake.in/when-not-to-use-array-prototype-map)
