JavaScript offers two main approaches to number formatting:

• Manual Formatting: You can create your own functions or use third-party libraries to manually format numbers.
• Library-Assisted Formatting: Use plugins or frameworks like jQuery Format, Numeral.js, or Intl.NumberFormat to streamline the process.

Library-Based Formatting Options

jQuery, a popular JavaScript library, provides several plugins for number formatting:

• autoNumeric: Offers customization, locale support, and a range of formatting options.
• jQuery Format: A comprehensive API that mirrors the functionality of Java's SimpleDateFormat and NumberFormat.
• jquery-numberformatter: Focuses on locale support, enabling internationalization.

Additional Formatting Considerations

• Currency Display: Use libraries like Intl.NumberFormat and formatCurrency.js for currency formatting.
• Locale Support: Many plugins and frameworks provide locale support, allowing you to format numbers according to regional preferences.
