String.prototype.trimStart() — leading tab

📖 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() — Tab Character

trimStart() also removes leading tabs.

Challenge: Implement removeLeadingTab(str) that removes a leading tab.

removeLeadingTab('\thello') // → 'hello'

💡 Hints (1)

• `trimStart()` removes all leading whitespace: spaces, tabs (`\t`), and newlines (`\n`).
