2019-11-25lib: flatten access to primordialsMichaël Zasso
Store all primordials as properties of the primordials object. Static functions are prefixed by the constructor's name and prototype methods are prefixed by the constructor's name followed by "Prototype". For example: primordials.Object.keys becomes primordials.ObjectKeys.

2019-07-25assert: avoid potentially misleading reference to object identityAnna Henningsen
Often, the word “identical” when referring to JS objects will be read as referring to having the same object identity (which is called “reference equality” here), but what the error message is trying to say here is that the objects are different but yield the same `util.inspect()` output. Since `util.inspect()` output represents the structure rather than the identity of objects, (hopefully) clarify the error message to reflect that.

2019-06-12assert: print more lines in the error diffRuben Bridgewater
So far consequitive identical lines were collapsed if there were at least three. Now they are only collapsed from five identical lines on. This also simplifies the implementation a tiny bit by abstracting some logic. PR-URL: https://github.com/nodejs/node/pull/28058 Reviewed-By: Rich Trott <rtrott@gmail.com>
2019-06-12assert: fix error diffRuben Bridgewater
In some edge cases an identical line could be printed twice. This is now fixed by changing the algorithm a bit. It will now verify how many lines were identical before the current one. PR-URL: https://github.com/nodejs/node/pull/28058 Reviewed-By: Rich Trott <rtrott@gmail.com>
2019-06-12assert: limit string inspection when logging assertion errorsRuben Bridgewater
This makes sure long strings as `actual` or `expected` values on an `AssertionError` won't be logged completely. This is important as the actual value is somewhat redundant in combination with the error message which already logs the difference between the input values.

2019-05-25assert: remove unreachable codeRich Trott
There is only one entry in `kReadableOperator` that ends in `Unequal`. So the value assigned on line 392 can only be truthy if `operator` is `notDeepEqual`. Therefore, the ternary condition on line 394 is always true. Remove the ternary. Coverage reports confirm that the removed code is unused.

2019-05-23assert: remove unreachable codeRich Trott
In lib/internal/assert/assertion_error.js, line 391 assures that `operator` is 'deepEqual' so there is no need to check the value of `operator` in a ternary on the next line (line 392).
