String.prototype.trimEnd() — no whitespace unchanged

📖 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.

A string without trailing whitespace is returned unchanged by trimEnd().

Challenge: Implement verifyTrimEnd(str) using trimEnd.
