Merged.

I will approve this fork as an update of the language version. The matter of the return value for non-alphabetic string needs to be approached on a higher level of the task definition, for all languages.

Updated to Node 18

Fixed (remember that you need to RESET the trainer to get the fixed code).

JavaScript sample tests do not import chai.

fourth time's the charm

JavaScript should be updated to Node 18 and use chai.
Updated in this fork

Not a bug. Since this Kata is still using Node v8, the sort is not stable, as this was not required at the time.
Since ECMAScript version 10 (ES2019), the specification dictates that Array.prototype.sort must be stable (preserve order). This was introduced to Node with version 12.

Modern browsers usually adhere to the newest specification, but it's good to keep in mind that programming only for the newest specification might break stuff for older browsers/systems.

Approved

JavaScript fork (author gone)

• Updated to Node 18 and chai
• Tests are now in line with the description (resolves this issue)
  • Backwards compatible, so old solutions will not be invalidated
• Does not address this issue, as per my comment.

O(1) formulas are only approximations for this problem. I don't see why solutions with an inaccuracy as high as 0.01 should be allowed.

Seems like a floating-point error. The tests should probably be changed to allow for precision errors (e.g. using assert.approximately instead of assert.strictEqual).
