String.prototype.padEndbeginner'5'.padEnd(3, '0') // β '500'
'hello'.padEnd(8, '-') // β 'hello---'
'hi'.padEnd(2) // β 'hi'Use padEnd() to pad the end of a string with a fill character until it reaches the target length.
str.padEnd(targetLength, padString?) pads the end of str with padString (default: space) until the total length reaches targetLength.
Challenge: Implement padRight(str, len) that pads with spaces to the given length.
padRight('hi', 5) // β 'hi '
