String.prototype.padStart(), String.prototype.padEnd()

The padStart and padEnd methods pad a string with some characters, until the resulting string reaches a given length. This can be useful for displaying text in a readable way, and especially so for aligning strings that are not of equal length as required by the user interface, or similar needs.
