Understanding Case Sensitivity in Variables - a bug?

Tell us what’s happening:

hey! I think I did everything right, but freeCodeCamp shows that I didn’t meet any requests & shows: “studlyCapVar is not defined” repeatedly.

Your code so far

// Declarations
var studlyCapVaR;
var properCamelCase;
var titleCaseOver;

// Assignments
studlyCapVar = 10;
properCamelCase = "A String";
titleCaseOver = 9000;

Link to the challenge:


your problem is that you defined var studlyCapVaR; at the beginning and tried to use studlyCapVar later. Those are two different things. If you want to reference something you defined, it has to be the same name.


Your two studlycasecapvar variables don’t match.
