Can you check against null explicitly.

Adds a new method signature variant for process.emitWarning()
that accepts an options object. The options object may include
a new `detail` option that allows additional detail text to be
associated with the warning. By default, this additional text
will be printed to stderr along with the warning, and included
on the Warning Error object using the `.detail` property.
e.g.
```js
process.emitWarning('A message', {
code: 'WARNING123',
detail: 'This is additional detail'
});
// Emits:
// (node {pid}) [WARNING123] Warning: A message
// This is additional detail
```

Should land with #12381. |
2 tasks
|
This will need to be manually backported if we want to land it. Thoughts? |
|
Perhaps we should backport it "lazily", i.e., backport it as soon another PR that we want to backport requires it? |
|
I'm fine with letting this one sit until it's necessary as @sam-github suggests. |
|
Release team were +1 on backporting to v6.x if someone wants to (not required). |

Adds a new method signature variant for
process.emitWarning()that accepts an options object. The options object may include a newdetailoption that allows additional detail text to be associated with the warning. By default, this additional text will be printed to stderr along with the warning, and included on the Warning Error object using the.detailproperty.e.g.
The primary use case for this is to allow additional information, such as links to Node.js documentation, expanded explanations, etc, to be included with the warning.
