Maybe enable Node 18 too, Sample Tests work on my machine with it... "Node 8's End of Life is December 31, 2019".

something is up with Ruby version, did not get values near enough. Used exact same formula in Python version and everything was ok.

I even set a default parameter for function addOrChangeUrlParameter(url, val = ""), but not working (Cannot read property 'split' of undefined,) It IS defined, always, even when not passed in..

fusc, fuscing fusc function !

maybe you "should" get more familiar with this website, before suggesting on changing its behaviour.

Yes. The description has not been changed yet ..

Not passing on part 1/2 error tests (getting Error or TypeError: fn is not a function), yet all part 2/2 tests pass.

"A very easy task for you!". Not for me, took too much time, abandoning trying.

logic, rather than just trying variations and seeing if one of them works?

setting global variable word = '' and returning undefined from function passes 220 tests but not 3 simple tests.. (actually the 3 simple tests are modifiable. Not submitting on this one.)

Seems like it is "performance/optimization" problem... I timed out with 45 passes (not even doing anything nested...)
