The `'close'` event is emitted when the stdio streams of a child process have
been closed. This is distinct from the [`'exit'`][] event, since multiple
processes might share the same stdio streams.
The `'close'` event is emitted after a process has ended _and_ the stdio
streams of a child process have been closed. This is distinct from the
[`'exit'`][] event, since multiple processes might share the same stdio
streams. The `'close'` event will always emit after [`'exit'`][] was
already emitted, or [`'error'`][] if the child failed to spawn.
```js
const { spawn } = require('child_process');
