Understanding Camel Case

Tell us what’s happening:
Unable to execute below Javascript code. I don’t see an issue but when compiling its throwing below error
studlyCapVar is defined and has a value of 10
Cannot read property ‘length’ of null

Your code so far

// Declarations
var studLyCapVaR;
var properCamelCase;
var titleCaseOver;

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

This doesn’t look like a proper camelcase. Remember to capitalize only first letters of each words like below words.

Got it. Thanks. it worked.
