String.prototype.trimEnd() — trailing spaces removed

📖 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()

str.trimEnd() removes whitespace from the end (right side) of a string only.

Challenge: Implement trimRight(str) that removes trailing whitespace.

trimRight('hello   ') // → 'hello'
💡 Hints (1)
  • • `trimEnd()` only removes whitespace at the end of the string.
