#1

// Parameter is a number, and we do math with that parameter
var timesTwo = function(number) {
return number * 2;
};

// Call timesTwo here!
var newNumber = timeTwo(8);
console.log(newNumber);

我哪裡錯了


#2

Make sure you check for spelling errors. timesTwo is spelt wrong when you tried to use it.


#3

You miss the 's' in timesTwo, when you call the function.
