PTAL. 

I think the patch reached the point where the preliminary review is possible.
Early feedback and iteration would be helpful!

|self| is the global scope, so there is no inheritance going on here this level.
I think this is okay and how it should work. (because testharness.js only works
on the main global scope.)

For my use case, this significantly improves the readability of the test result.

This method is confusing. I thought it's clever to detect a NaN or NaNs in an
array, but both the result and the intention are confusing. (Just like you
misread the name...)

This one is also a bare bone design of the summary report. It seems like it's
not really necessary after introducing 'actual description' in should().

I should rename the variable to |passed|.  The third else clause handles the
case where it throws but with a wrong error type.

Nope. The comments are same. I didn't use the example though - because the
syntax has been changed.

1) Examples in the comment.
2) Live examples in the unit test HTML.

Recall we used to print out a short summary and a verbose output (because
verbose was the default).  The verbose output included something like


Index    Actual   Expected  Diff   RelError
1        1        2         1      0.5
2        2        3         1      0.3333

Max diff of ddddd at index kkkk
Max relError of rrrrr at index nnnnn.

Super useful when thresholds depend on the platform so you can use trybots to
get the appropriate thresholds.

Yes, that's much clearer.  Or just say the array contains only the values in
|expected| in the order of values in |expected|.

Prefer 1 because it's easier to find; I won't be looking at the unit-test html
when trying to figure this out.

If the example it too long, then reference the unit-test html, I guess.  (Or
both).

And maybe at the top of this file add a reference to the unit-test file.  I
think this also means the unit-test file should exercise all possible options
for every single method here.

Is there a way to mark a test as expected to fail?  That would be really useful.
(I suspect testharness doesn't allow that.)

PTAL.

Many parts were replaced/removed for the clean up and refactoring. Also updated
the printed output in the CL description accordingly.

This method is removed. It's better to use isNaN() or Array.includes(NaN).

I scaled down to a single case (object/array), but we can expand if needed in

Oh, I misunderstood your comment. Added comments about the optional arguments to
