This is so smart!

Amazing, really improved my understanding of the possibilities of reduce!

Good job, applause!

wonderful!

its amazing!!!

I had some fun after that comment. ;)

Kucharskimaciej your comment above is incorrect. +v is not an equivalent of parseInt(v, 10). It is, in fact, an equivalent of Number(v). The '+' operator is a shorthand to coerce each 'v' from a string to a number.

This might seem like splitting hairs, but it’s a critical point for others to understand this shorthand in a broader context.

In the solution above, we see that 'int' is already coerced into a number because of the *256. If we step through the first loop of the reduce method without coercing 'v', we can see how the sum would change — 128 * 256 + "32" // "3276832" (INCORRECT) vs 128 * 256 + 32 // 32800 (CORRECT). Without coercing 'v' you actually coerce 'int' back into a string and concatenate 'v'

I adore you.
This is so crazy and magic that I haven't seen before

awesome!

This is the coolest solution i have seen so far on codewars.

+v is an equivalent of parseInt(v, 10)

I guess I'm a rebel then! :)

it wasn't at the begining
