Abbreviation gone wrong.

I don't know what to do with this thing. I've tried a couple of things but still haven't figure it out.

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);

we need to map over the daysOfWeek array and for each element we slice the day, the map function returns a new array so we can save that to the abbreviatedDays variable

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

abbreviatedDays = daysOfWeek.map((day) => {
  return day.slice(0, 3);
});

Thank you for this one. This is my first time hearing the slice method, I believe it was not mentioned in the video before this code challenge or I must've just missed it. But, thanks so much!
