You were missing the return in the default
All that code could be written like this
const vals = { "sun": 9, "mon": 8, "tue": 7.5, "wed": 6.75, "thu": 6, "fri": 8.25, "sat": 10 };

day = day.toLowerCase().slice(0, 3);
const sleep = vals[day]; // if found
return sleep || "Re-enter a day of the week only. The following entries are valid: monday, Monday, mon or Mon etc.";
};
console.log(getSleepHours("Monday")); //result should = 8
console.log(getSleepHours("td")); //*result should = default message, but logs 'undefined'.*
console.log(getSleepHours("Wednesday")); //result should = 6.75

您错过了默认的回报，
所有代码都可以像这样编写
