Time representation difference in Chai.js

[keithamus]

Oh yeah 😅 I was reading it wrong. Let's change chai 😄

[flaambe]

@keithamus Yeah, thanks, it worked

At the moment I have 15 failed tests

Let's change it here - ISO dates lead to less confusion.

[flaambe]

I think you meant in chai, since loupe uses ISO, or I'm wrong?))

I can't figure out what the problem is:

  5) expect
       within(start, finish) (dates):

      expected 'blah
      + expected - actual

      -blah: expected 2021-01-27T12:03:21.949Z to not be within Wed Jan 27 2021 17:03:21 GMT+0500 (Uzbekistan Standard Time)..Wed Jan 27 2021 17:03:22 GMT+0500 (Uzbekistan Standard Time)
      +blah: expected 2021-01-27T12:03:21.949Z to not be within 2021-01-27T12:03:21.949Z..2021-01-27T12:03:22.949Z

this probably needs to change to something like

range = loupe(start) + '..' + loupe(finish)

There'll likely be a few of these behavioural changes within the code. Part of the motivation for moving to using loupe is to standardise this kind of edge case behaviour.
