Full Stack JavaScript Techdegree Student 876 PointsWhat if both values are not a number
How would you do condition when both numbers are in string and would like to test it in console.log? As long as the conditional statement provides only one option it will always be Error with the message "Provide a lower number" only
Thank you for your anwer
function getRandomNumber(lower, upper = 100) { if(isNaN(lower)) { throw Error("Provide a lower number") }else if (isNaN(upper)){ throw Error("Provide a higher number")

} }
console.log( getRandomNumber("five", "six") );
