const likes = ([a, b, c, ...xs]: string[]): string =>
    a === undefined
        ? "No one likes this."
        : b === undefined
            ? `${a} likes this.`
            :  c === undefined
                ? `${a} and ${b} like this.`
                : xs.length === 0
                    ? `${a}, ${b} and ${c} like this.`
                    : `${a}, ${b} and ${[c, ...xs].length} others like this.`;
