[4.6 in Readme](https://github.com/airbnb/javascript#arrays--callback-return) last example is shown as ``` inbox.filter((msg) => { const { subject, author } = msg; if (subject === 'Mockingbird') { return author === 'Harper Lee'; } return false; }); ``` but its not a example of `arrays--callback-return`, its illustrate `avoid of else`, when using return statement.
