Took 2 weeks to solve, but I had a lot of fun, and learned a lot on the way!!

Something is wrong with the Duplication exception tests

TSError: ⨯ Unable to compile TypeScript:
test.ts:608:16 - error TS18046: 'e' is of type 'unknown'.

608         expect(e.message).to.equal('Duplicate ' + duplicate);

I did comment it out from my sample tests, and it allowed my solution to pass all tests.

I also, tried other users solutions, and they do not pass this test case as well.

Guys, I updated the description and added an example of how steps are counted, it should make the kata a bit better

People can index into strings just as well as they can index into arrays.

that's not true in JavaScript where strings are arrays of UTF-16 code-units. "🐸"[0] !== "🐸". I know that you know how to get around this, but many beginners do not, so i fell like it's not completely unwarranted to pass an array of codepoints

But spitting the inner string into an array of characters ( encoded as strings, because JS doesn't have characters ), doesn't add anything.

People can index into strings just as well as they can index into arrays.

All you're doing is adding visual clutter.

.

Done

it's still not sufficient. My original solution still passes. There needs to be a lot more random tests, something like 100-200

Increased the difficulty

testing really needs to be beefed up. Look at my solution

?

Yeah, but it is a matrix exercise

["0", "0", "🐍", "0", "🐸"]

Congratulations. You have invented the String.

Sorry, I left confusing description, I'll fix it

• Can we jump diagonally? Manhattan or Euclidian distance?
• Where do the jump points come from?
• What is the map encoding?
• An example of the map would be nice.

It was the hardest 8kyu to me ;)
