good idea

;-)

Thanks ;-)

If this is in reply to

You are only ever testing the generated function with input 3. That's not really a random test, is it?

it would have been clearer if you had actually replied to that comment.

Anyway. Look at the subtle difference between

const create = n => Array.from( {length: n }, (_,i) => n => n+i ) ;

and

const create = n => Array.from( {length: n }, (_,i) => () => i+3 ) ;

Both pass.

One of them does not implement the spec.
