The image is unavailable, so there is no example now.
First I was amazed at the input image. But five minutes later I understood it was not the actual example but the 'unavailable' plug.

it should be told to the user that the x/y axis aren't those used usually for 2D arrays indexing (for now, there is only an hint about it far, far away from the top of the description...)

Enjoyed this Kata, thanks. Might be nice to have sample tests that contain some of the weirder characters that can crop up in the random tests, maybe?

const image1={data-uri} //image 1
const image2={data-uri} //image 2

This information is redundant and misleading. Function accepts image, which is {data-uri}. image1 and image2 do not matter.

Needs random tests

Comparing images (even if it's ASCII art) with 100% accuracy required is ridiculous.

It's just like floating point error, but worse.

Coffeescript translation

Also, the initial code has the wrong syntax.

n = 1
Expected: '10^0', instead got: '1'

Isn't this just a combination of many duplicates?

Now that my complex gamma function kata has been approved, this kata essentially becomes a duplicate of it.

This is still a duplicate.

MichaelSel, you need to block the use of indexOf() function too.

Ruby and Python translations, please check and accept :-)
