JavaScript JavaScript Foundations Arrays Methods: Part 1

2 array methods at once?

For the first question in this quiz it's asking us to add a word to the beginning of the array and simultaneously remove it. Isn't that like using unshift() and shift() at the same time?

The wording of the question is a little confusing... They're not actually asking you to add a word to the beginning of an array, but simply to assign the first word of the "spareWords" array to a variable named "firstWord".

var firstWord = spareWords.shift();
