Code works perfectly fine in my browser but shows wrong answer here. 

var players = ['Jim', 'Shawna', 'Andrew', 'Lora', 'Aimee', 'Nick'];
console.log(players[0]);

var num = players.length - 1;
console.log(players[num]);
script.js 
var players = ['Jim', 'Shawna', 'Andrew', 'Lora', 'Aimee', 'Nick'];
console.log(players[0]);
var num = players.length - 1;
console.log(players[num]);

The compiler on Treehouse is being picky and would like you to use an actual number. You are correctly accessing the array though. Either move the assignment for num into the brackets or just use [5]:

i.e.

console.log(players[players.length - 1])

// or

console.log(players[5])

Awesome! Thank you! I was worried that passing ".length" when working with arrays was not allowed by the JS which made no sense.
