Bug?

My solution returns the correct output, but it fails me and tells me forEach was not used! What's up with that?

app.js 
const days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
let dayAbbreviations = [];

// dayAbbreviations should be: ['Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa']
// Write your code below

Object.keys(days).forEach(key => dayAbbreviations.push(days[key].slice(0,2)));

Hi Eric,

I imagine the test logic is looking for days.forEach() and other approaches at solving it throw it off.

If you alter your answer to omit Object.keys() you should be able to move on:

days.forEach(day => dayAbbreviations.push(day.slice(0,2)));

I get your same error if I swap out the variable:

let test = days;
test.forEach(day => dayAbbreviations.push(day.slice(0,2)));
