JavaScript: Tips of the Day

Add padding to the beginning of a string

const name = 'Minta Lofton';
console.log(name.padStart(13));
console.log(name.padStart(2));

With the padStart method, we can add padding to the beginning of a string. The value passed to this method is the total length of the string together with the padding. The string "Minta Lofton" has a length of 12. name.padStart(13) inserts 1 space at the start of the string, because 12 + 1 is 13.
If the argument passed to the padStart method is smaller than the length of the array, no padding will be added.
