Why this is wrong?

JavaScriptLoops and arrays class : Challenge Task 1 of 2 , I think below is correct but the program says it's wrong. I would like to know why ? thank you.

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

script.js 
var players = ['Jim', 'Shawna', 'Andrew', 'Lora', 'Aimee', 'Nick'];
index.html 
<!DOCTYPE html>

<script src="script.js"></script>

You are close. You don't need the "int" which isn't actually for anything.

players.length - 1 //this will give you an integer

if you wanted to add in what you were trying to do, you would use parseInt which would take a string and parse it into an integer if possible. In this case players.length is already an integer.
