191 <p><code>removeListener()
</code> will remove, at most, one instance of a listener from the
192 listener array. If any single listener has been added multiple times to the
193 listener array for the specified
<code>eventName
</code>, then
<code>removeListener()
</code> must be
194 called multiple times to remove each instance.
</p>
195 <p>Once an event is emitted, all listeners attached to it at the
196 time of emitting are called in order. This implies that any
<code>removeListener()
</code> or
<code>removeAllListeners()
</code> calls
<em>after
</em> emitting and
<em>before
</em> the last listener finishes execution
197 will not remove them from
<code>emit()

200 <p>Because listeners are managed using an internal array, calling this will
201 change the position indices of any listener registered
<em>after
</em> the listener
202 being removed. This will not impact the order in which listeners are called,
203 but it means that any copies of the listener array as returned by
204 the
<code>emitter.listeners()
</code> method will need to be recreated.
</p>
205 <p>When a single function has been added as a handler multiple times for a single
206 event (as in the example below),
<code>removeListener()
</code> will remove the most
207 recently added instance. In the example the
<code>once(
'ping

</code>listener is removed:
