Tell us what’s happening:
In this task I have changed properCamelCase in a correct way, both in assignment and declaration, still I am getting an error if any one can help me out will be appreciated.

Your code so far

// Declarations
var studlyCapVar;
var properCamelCase;
var titleCaseOver;

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