I am not able to solve it help me

Your code so far

var anotherVariableName;
var thisVariableNameIsTooLong;
var properCamelCase;
var titleCaseOver;
// This is the right answer:

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

studlyCapVar = 10;
titleCaseOver = "camelCase";
titleCaseOver = 9000; //"camelCase";```
