Rich Trott	380929ec0c	test: remove common.noop This change removes `common.noop` from the Node.js internal testing common module. Over the last few weeks, I've grown to dislike the `common.noop` abstraction. First, new (and experienced) contributors are unaware of it and so it results in a large number of low-value nits on PRs. It also increases the number of things newcomers and infrequent contributors have to be aware of to be effective on the project. Second, it is confusing. Is it a singleton/property or a getter? Which should be expected? This can lead to subtle and hard-to-find bugs. (To my knowledge, none have landed on master. But I also think it's only a matter of time.) Third, the abstraction is low-value in my opinion. What does it really get us? A case could me made that it is without value at all. Lastly, and this is minor, but the abstraction is wordier than not using the abstraction. `common.noop` doesn't save anything over `() => {}`. So, I propose removing it.

test: remove common.noop

This change removes `common.noop` from the Node.js internal testing
common module.

Over the last few weeks, I've grown to dislike the `common.noop`
abstraction.

First, new (and experienced) contributors are unaware of it and so it
results in a large number of low-value nits on PRs. It also increases
the number of things newcomers and infrequent contributors have to be
aware of to be effective on the project.

Second, it is confusing. Is it a singleton/property or a getter? Which
should be expected? This can lead to subtle and hard-to-find bugs. (To
my knowledge, none have landed on master. But I also think it's only a
matter of time.)

Third, the abstraction is low-value in my opinion. What does it really
get us? A case could me made that it is without value at all.

Lastly, and this is minor, but the abstraction is wordier than not using
the abstraction. `common.noop` doesn't save anything over `() => {}`.

So, I propose removing it.

events: add eventNames() method

Per https://github.com/nodejs/node/issues/1817, there are many modules
that currently abuse the private `_events` property on EventEmitter.
One of the ways it is used is to determine if a particular event is
being listened for. This adds a simple `eventNames()` method that
returns an array of the events with currently registered listeners.
