> Strip the final [newline character](https://en.wikipedia.org/wiki/Newline) from a string/buffer
|
|
|
|
Can be useful when parsing the output of, for example, `ChildProcess#execFile`, as [binaries usually output a newline at the end](https://stackoverflow.com/questions/729692/why-should-text-files-end-with-a-newline). Normally, you would use `stdout.trim()`, but that would also remove newlines at the start and whitespace.
