This is great!
I wish everyone would read this. :)

I have been trying to subtlety nudge my other team members in this direction.
Especially in regards to pure functions.

Code usually becomes much more destructured, easier to refactor, re-use, etc.
When using concepts like these, in my experience. :)

 

Really glad you like it. I tried to not get overly complex and explain it as simply as I could... My joke is if I can explain it to my none technical friends and family then it's ready... This could still be better 😆😅

Thank you! 😁

 

const twoAddedPointFree = arr.map(addTwo) // [ 3, 4, 5]

 

🤣🤣🤣🤣 I math'd wrong 😅😅😅

Thank you! 😁

 

Welcome! You know it'd be great if you add some examples of the perils of mutating objects / data in an app, and how it can lead to debugging nightmare. Just a thought.
