String.prototype.trimStart() — trailing spaces preserved

📖 Usage Example

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

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

String.prototype.trimStart() — Trailing Spaces Preserved

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

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

trimStartOnly('  hello  ') // → 'hello  '
