assert: add strict functionality export by BridgeAR · Pull Request #17002 · nodejs/node

BridgeAR · 2017-11-13T22:50:55Z

To further improve assert this adds a strict export. When used, all functions will use the strict equality instead of a loose one.

At the same time this is a doc only deprecation of the legacy loose mode. It is not intended to remove the old functionality as it is wildly used a lot and removing it does not seem to be a option.
I also improved the assert documentation in general a bit. It now outlines the used rules a bit better and clearly separates loose and strict equality.

Bold move. I like it in theory, but I'd caution that we are probably never going to be able to get rid of legacy mode, so we will need to support both strict and legacy mode forever... I'm not objecting, but I am being cautious...;.

Nit: comma after property?

Trott · 2017-11-14T00:10:31Z

doc/api/assert.md

Nit: Put everything after e.g. and up to the closing . in parentheses.

Nit: Here and several places above, function names should be followed by () I believe. So assert.deepEqual() rather than assert.deepEqual. That said, if there's already a lot of no-parentheses examples in the doc, never mind. :-D

Trott · 2017-11-14T00:11:49Z

doc/api/assert.md

Nit: They're called non-strict, legacy, and loose throughout the document. I'd suggest picking just one of those and sticking with it.

Nit: are often not sufficient might be better expressed as can often have surprising results.

I rephrased it and hope it is clearer now :-)

BridgeAR · 2017-11-14T02:29:34Z

@Trott I addressed all comments. I know it might seem a strong move but we do not have to remove the legacy mode ever and that is also why I only wanted a doc only deprecation.
Having the strict mode will likely improve the situation for many people though.

refack

Quick LGTM

Would it be just #assert_strict_mode? As it is not an assert API part, just a simple heading.

[ strict mode`][]: space instead of a backtick.

Needs another rebase :-)

1) Separate all loose and strict functions. 2) Stronger outline the used comparison rules in (not)deepStrictEqual 3) Fix SameValue comparison info

Requireing the strict version will allow to use `assert.equal`, `assert.deepEqual` and there negated counterparts to be used with strict comparison instead of using e.g. `assert.strictEqual`. The API is identical to the regular assert export and only differs in the way that all functions use strict compairson.

BridgeAR · 2017-11-23T09:21:18Z

Rebased plus some tiny documentation improvements while doing so (it is actually the SameValue comparison used by Object.is() and not the Object.is() comparison).
