Copied some basic tests to the sample tests. Fixed.

Don't bother! I figured it out myself. By the way, +1 for good use of splice.

Looking at your code, I see you added a third argument to splice.

tempArr.splice(index, 1, ' ');

How come that fixed the solution?

Thanks... After a small tweak of my code it now passes all tests...!

What I did find though was that when it was failing, if I re-submitted the exact same code it would fail different amounts of tests - which made finding my error a bit more of a challenge.

Try again, it seems to be working fine under Nodev6.11.
Of course, some test cases are failing, but they are only a few.

There nolonger appear to be any 'tests' for the javaScript version of this Kata.
