NEED SOME HELP

Use the map method on the daysOfWeek array, creating a new array of abbreviated week days. Each abbreviated string should be the first three letters of the long version in daysOfWeek. Store the new array in the variable abbreviatedDays.

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

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

Using Shlomi's suggestion: try:

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

Hi Humoyunmirzo Nosirov, In the call for map you need to pass a function. Something like this: let abbreviatedDays = daysOfWeek.map(day => day.substr(0,2));
