Understanding Case Sensitivity in Variables, freeCodeCamp Basic Javascript

Lesson Summary

In this challenge we learn the importance of case sensitivity in javascript. It is programming convention to lower case the first word of our variables, but upper case every subsequent first letter in additional words of the variable for example if we declare a variable that contains 3 words we would declare in this fashion, " var = threeWordVariable ". Notice the first word three is all lower case, but every subsequent word has the first letter capitalized.
