I don't understand the issue

Question: "The variable 'thirdElementInArray' was supposed to be the third element in the array. Fix the code so it 'thirdElementInArray' is the actual third element in the array."

Answer (given in the working area): 

var my_array = ["sugar", "rush", "fix", "it", 3.14, 42];
var thirdElementInArray = my_array[3];

Hi,

Arrays in Javascript and most other programming languages use zero-based indexing. This means that when counting the order of items in the array, you need to start with 0.

    var array = ['first', 'second', 'third'];

    var firstElementInArray = array[0]; // First element has the index of 0 - zero
    var secondElementInArray = array[1];
    var thirdElementInArray = array[?]; // Replace ? with the correct number.
