No, the tests are terrible

I wrote the rails out using 4 rails, gives you all the insights. For decoding I used the same strategy, but i was able to use patterns from the encoding code.

beautiful

My edit-array method is about 20 times faster than my edit-string method

that's an issue with forking, not with the kata itself

With javascript, when i fork and then run the tests, there is an error:

ReferenceError: Test is not defined
    at /workspace/node/test.js:11:1
    at Object.<anonymous> (/workspace/node/test.js:66:3)

Please change the first paragraph description:

John and Mary stay on a camping and want to visit a few towns. Mary has on a sheet of paper a list of distances to drive back and forth to these towns. ls = [50, 55, 57, 58, 60]. John is tired of driving and he says to Mary that he doesn't want to drive more than t = 174 miles and he will visit only 3 towns and visit one town a day. Mary agrees provided they visit no less than 3 towns.

impressive, looks like a slender bird

Yes, could you read the link I gave you and see for yourself, what you're doing wrong?

Array.sort gives you the opportunity to sort on any property, also on numeric properties.

Yes, but comparing numbers, and it was wrong (the way you did it).

I was sorting words

That's not how you use sort, read this. A problem with your code is not a kata issue.
