I am no developer, no IT-spezialist.
In real life I am only a doctor...
JS war my fan, relax, kind of art:)

It is just art:)

IIFE & NFE & recursion

Auf keinen Fall!
It was my Art:)

Yes, it war my art...

This is functional library RAMDA

These are characters from glagolica alphabet.

This is destructuring with ASHII trick :)

'rеturn' is a tag function, not a reserved word:)

Yes, you are technically wright.
I've just only wanted to avoid nested functions.
I put all functions to one curly brace block.
If I do so - all subfunctions is syntactically more complex, but also more universal.
For exemple, my curried function check(arr)(x) do not relay on the scope of the outer function (argument arr), but can be used out of this scope.

Yes, but I only try to solve kata with using different JS features
It is my internal task:)

Got it, thanks!

Why it do not work at me?
How you pass tests in JS?

It is a plain JavaScript without any moduls.

Yes,

{const {pipe, adjust, inc, apply, range} = require('ramda');
var generateIntegers = pipe(Array, adjust(inc, 1), apply(range))}

will be better, but longer :)
