Bummer: Line 7: Unexpected token ILLEGAL in slice solution.

I am getting this code to work in my code editor (vscode) but I get: "Bummer: Line 7: Unexpected token ILLEGAL in slice solution." when I'm doing the challenge.

app.js 
const daysOfWeek = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
let abbreviatedDays;

// abbreviatedDays should be: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
// Write your code below

abbreviatedDays = daysOfWeek.map(days => `${days.slice(0, 3)}`);

I'm not sure why it doesn't work in the Challenge, but, really, there is no need for the template literal as it's redundant and we're not adding any extra text.

Remove the template literal and placeholder syntax so you end up with, days.slice(0, 3);

Hi Joel, try the following:

abbreviatedDays = daysOfWeek.map(day => day.substr(0,3));

Hey Shaun, thanks! But I really wasn't looking for a complete solution. I managed to complete the task, but I was just curious to why my code didn't work. Cheers / Joel
