String.prototype.padEnd() — no padding when already long enough

📖 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() — No-Op

If str.length >= targetLength, .padEnd() returns str unchanged.

Challenge: Implement padToTen(str) that pads to length 10.

padToTen('hello world!') // → 'hello world!'  (unchanged, already > 10)
padToTen('hello')        // → 'hello     '

💡 Hints (1)

• If the string is already at or beyond the target length, `.padEnd()` returns it as-is.
