Suggested change
if (invertedRobot[value] !== undefined
|| Object.values(invertedRobot).includes(value)) {
return null;
}
if (invertedRobot[value] || Object.values(invertedRobot).includes(value)) {
return null;
}

Actually the second condition looks redundant


invertedRobot[value] = key;
}

return invertedRobot;
}

module.exports = inverseRobot;
