JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Using Array Indices

Does Challenge Task 2 in JavaScript Loops, Arrays and Objects have a mistake in the software?

The question reads as follows: Use console.log() to log out the last item in the array. var players = ['Jim', 'Shawna', 'Andrew', 'Lora', 'Aimee', 'Nick'];

Here's my answer: console.log(players[5]);

I've tried all numbers from one through six and nothing works.

var players = ['Jim', 'Shawna', 'Andrew', 'Lora', 'Aimee', 'Nick'];
console.log (players[6]);

The first index you tried (5) is indeed the correct one. The issue is that you have removed / changed the code you wrote in task 1. Below the challenge description of every task the following text is written:

Important: In each task of this code challenge, the code you write should be added to the code from the previous task.

What that is trying to tell you is that for multi-part challenges you should not remove previous parts, but add to them. When you try to check your code the challenge checker will run all of the tests from all of the tasks it has given you so far, and if your code does not pass all of them (not just the test for the current task) then it will be marked invalid.

So if you add the code for task 1 back like this:

var players = ['Jim', 'Shawna', 'Andrew', 'Lora', 'Aimee', 'Nick'];

Then your code will pass.
