Someone answer this

Continuing the discussion from Discouraged about how my code looks :slightly_frowning_face::

const getI = r => +!r?.employee?.foo

The ! is the logical NOT operator, so it will take whatever r?.employee?.foo returns and convert that value to its opposing boolean value (i.e if r?.employee?.foo returned a falsy value then ! will convert it to true and vice versa).

The + operator will then forcibly convert that boolean value into a number (either 0 or 1).
