Hmmm, now you are mutating fruit array.
Are you sure you were not trying to do something like

const fruitsAndVegetables = fruits.concat(vegetables);
const fruitsAndVegetables = fruits.slice();
fruitsAndVegetables.unshift('carrot');

I don't believe there is a neat little 1 liner to do the equivalent without wrapping 'carrot' in a temp array.

I feel the same way...the new syntax is much more compact.
