String.prototype.trim() — no whitespace unchanged

📖 Usage Example

'  hello  '.trim()      // → 'hello'
'
 text 	'.trim()   // → 'text'
'no spaces'.trim()   // → 'no spaces'

Use trim() to remove all leading and trailing whitespace characters from a string.

String.prototype.trim() — No Whitespace

If the string has no leading or trailing whitespace, .trim() returns an equivalent string.

Challenge: Implement trimClean(str) and verify it works on clean strings.

trimClean('hello') // → 'hello'
