Treehouse TeacherHi there! You're doing great, and this trips up a lot of people. On the plus side, you've got all the components, but they're a little out of order.
First, we say what we want to happen, then we give the condition, and then we give the two alternatives. Take a look:
textColor = (value < 0) ? "red" : "green";
In the first part, we say that we want a color assigned to textColor. Next, we give the expression this should be dependent upon. And lastly, we say the two alternatives. The first one will be what happens when the expression evaluates to true and the second is what happens if it evaluates to false. So the textColor =
is the thing that "happens". The (value < 0)
is the expression that's being evaluated. Then we insert a question mark. The thing on the left of the colon is the value assigned if it's true. The thing on the right is the value assigned if it is false.
Hope this helps!
