JavaScript JavaScript Array Iteration Methods Array Manipulation Practice map()

map() with template literals in JavaScript

Hi there,

I'm doing the following challenge: https://teamtreehouse.com/library/javascript-array-iteration-methods/array-manipulation/practice-map

My code is not passing: abbreviatedDays = daysOfWeek.map(day => `${day[0]}${day[1]}${day[2]}`);

I tested it elsewhere and it outputs the correct result, ['Sun', 'Mon', 'Tue', ... etc]

Any idea what I'm missing?


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(day => `${day[0]}${day[1]}${day[2]}`);

Apparently, this challenge doesn't allow template literals. Try using concatenation instead.

If you consider this a bug, you might want to report it to the Support folks.

Thanks. Concatenation did indeed work. With that being the case, I can't see why template literals wouldn't. Will shoot them a message
