String.prototype.trim() — both ends

📖 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() — Both Ends

.trim() strips whitespace from both the start and end simultaneously.

Challenge: Implement trimBoth(str) that removes whitespace from both ends.

trimBoth('  hello  ') // → 'hello'
