String.prototype.padEnd() — custom fill string

📖 Usage Example

'5'.padEnd(3, '0')       // → '500'
'hello'.padEnd(8, '-')   // → 'hello---'
'hi'.padEnd(2)           // → 'hi'

Use padEnd() to pad the end of a string with a fill character until it reaches the target length.

String.prototype.padEnd() — Custom Fill

Pass a second argument to use a custom fill string instead of spaces.

Challenge: Implement padDots(str, len) that pads the end with dots '.'.

padDots('hi', 6) // → 'hi....'
