Storing whole linked list in an array is pointless.
You use all-in-memory structure to walk through light one.

True if True else False

Can someone look at this translation and to verify them?

Thank you :)

Improved!

Thanks guys.

"value/array starts with..." suggest: "first indexes should be
[1, 2, 3]".
"Initial array/value should be..." would be better.

If your implementation use map function to fill new Array of empty elements x is every element, it means null :)
This param isn't useful, by is necessary to provide 2nd index by map notation. It simplifies implementation.

I had the same.
Remove 'use strict'; if you set.

Clever, but ineffective.
You try to guess nextBigger by sorting and comparig arrays nexteBigger - n times.

In the case of 59884848459853 it's 23706 times :)

I just add random test to Clojure ver.

if (true) fixed();

Fixed!

You convinced me.
Try now ;)
