PadStart y Padend JavaScript
// padStart pads a string with a given character until a certain
// length is reached. An empty character is used if second param is omitted.
const example = 'Dylan';
console.log(example.padStart(10, 'a')); // aaaaaDylan
// padEnd would place the padding at the end
console.log(example.padEnd(10, ‘a’)); // Dylanaaaaa
