String.prototype.trimEnd() — leading spaces preserved

📖 Usage Example

'  hello  '.trimEnd()   // → '  hello'
'text   '.trimEnd()    // → 'text'
'hi'.trimEnd()         // → 'hi'

Use trimEnd() to remove only trailing whitespace from the end of a string, leaving leading whitespace intact.

String.prototype.trimEnd() — Leading Spaces Preserved

trimEnd() does NOT touch the leading whitespace — only trailing whitespace is removed.

Challenge: Implement trimEndOnly(str) that removes trailing but preserves leading whitespace.

trimEndOnly('  hello  ') // → '  hello'
