`A.takeWhile` acting like `A.filter`

[ssnielsen]

First of all, thanks for a solid library - it's really a breeze to use!

While doing a bit of Advent of Code, I noticed unexpected output from A.takeWhile - essentially it seems to act more like A.filter

Examples:

// ts-belt:
A.takeWhile([3, 5, 3], n => n < 4); 
// Returns [3, 3]

I'd expect to get back the single-element list: [3].

Ramda (and other similar libraries):

// ramda:
R.takeWhile(n => n < 4, [3, 5, 3])
// Returns [3]

Smells a bit like a bug to me 😉

Also - looking at a bit further, it looks like this case isn't covered by the tests

Btw, the version in question is 3.13.1

Btw, if you're ok with it, I'm definitely willing to give it a go at fixing it 😉 (forgot to say that above)

@ssnielsen thanks for spotting this issue! indeed, takeWhile was implemented incorrectly, I fixed it up in v4.0.0-rc.2 :)

test case: https://github.com/mobily/ts-belt/commit/235f223a879fc45cc1a2da7cf27d8cf78d15a4e0#diff-39838e57d36e74e0f3b610bc317412d00c08c0f67a99d5b8f1cae4784ae33cfbR9

Any chance this fix might be back-ported to v3?
