/*The push() method adds elements to the end of an array, and unshift() adds
elements to the beginning.*/
let twentyThree = 'XXIII';
let romanNumerals = ['XXI', 'XXII'];
romanNumerals.push(twentyThree);
// now equals ['XIX', 'XX', 'XXI', 'XXII', 'XXIII']
romanNumerals.unshift('XIX', 'XX');
// now equals ['XIX', 'XX', 'XXI', 'XXII']
>>> a.push(...b)
