Answer 1

You could get the two last elements and join them with ' and ' and put it as last element back into the array and later join all elements with ', ' for getting a nice string.

Methods

• Array#concat, joins two arrays and returns a new array

• Array#splice, for getting the last two elemensts of the array

• Array#join, joins an array with the given spacer.

This proposal works for any length of an array, even with one or two elements.

function nice([...array]) {
    return array.concat(array.splice(-2, 2).join(' and ')).join(', ');
}

console.log("Content tagged " + nice(['tag1']));
console.log("Content tagged " + nice(['tag1', 'tag2']));
console.log("Content tagged " + nice(['tag1', 'tag2', 'tag3']));
