Currency Formatting
- numeral:
numeral provides a flexible formatting system that can format numbers as currency, percentages, and more. It allows for extensive customization of the output format, making it suitable for applications that require diverse number formatting.
- currency.js:
currency.js allows you to format currency values easily, but its primary focus is on arithmetic operations. It provides methods to format numbers as currency strings, ensuring that the output adheres to the specified currency format.
- dinero.js:
dinero.js offers comprehensive currency formatting capabilities, allowing you to format money objects into strings with specific currency symbols and formats. It supports localization and can handle various currencies seamlessly, making it ideal for international applications.
- currency-formatter:
currency-formatter provides simple methods to format numbers as currency strings based on locale and currency type. It supports various currencies and allows customization of decimal and thousand separators, making it easy to display currency values correctly.
Arithmetic Operations
- numeral:
numeral does not focus on arithmetic operations but can format numbers after calculations are performed. For arithmetic operations, you would need to use standard JavaScript methods or combine it with other libraries.
- currency.js:
currency.js excels in performing accurate arithmetic operations on currency values. It ensures that calculations maintain precision, making it suitable for applications that require financial computations without rounding errors.
- dinero.js:
dinero.js is designed for complex arithmetic operations, allowing you to perform addition, subtraction, multiplication, and division on money objects. It maintains immutability, ensuring that operations do not alter the original value, which is crucial for financial applications.
- currency-formatter:
currency-formatter does not support arithmetic operations; it is strictly for formatting purposes. If calculations are needed, additional logic must be implemented separately.
Localization Support
- numeral:
numeral provides some localization features, but its primary focus is on number formatting rather than currency-specific localization. Developers may need to implement additional logic for comprehensive localization.
- currency.js:
currency.js has limited localization support primarily focused on formatting. It does not provide extensive locale management, so developers may need to handle localization separately if required.
- dinero.js:
dinero.js supports localization by allowing you to specify currency codes and formats. It is well-suited for applications that need to handle multiple currencies and ensure that values are displayed correctly based on user preferences.
- currency-formatter:
currency-formatter supports multiple locales, allowing developers to format currency according to regional standards. This feature is essential for applications targeting international users, ensuring that currency displays are appropriate for different cultures.
Immutability
- numeral:
numeral does not focus on immutability. It is primarily a formatting library, and while it can handle numbers, it does not enforce immutability in its operations.
- currency.js:
currency.js does not enforce immutability, which means that operations can change the state of currency objects. This can lead to potential issues if not managed carefully, especially in complex applications.
- dinero.js:
dinero.js emphasizes immutability, meaning that every operation returns a new instance of the money object rather than modifying the original. This feature helps prevent unintended side effects and makes it easier to manage state in applications.
- currency-formatter:
currency-formatter does not deal with mutability as it is primarily a formatting library. It does not create or manage state, so immutability is not a concern.
Complexity and Learning Curve
- numeral:
numeral is easy to learn and use, especially for those familiar with number formatting in JavaScript. Its flexible API allows for quick implementation, making it accessible for developers of all skill levels.
- currency.js:
currency.js has a moderate learning curve due to its focus on arithmetic operations. Developers need to understand how to use its methods effectively to manage currency calculations, but it is still relatively easy to pick up for those familiar with JavaScript.
- dinero.js:
dinero.js may have a steeper learning curve due to its comprehensive feature set and focus on immutability. Developers may need to invest time in understanding its API and concepts, but it provides powerful tools for managing money effectively.
- currency-formatter:
currency-formatter is straightforward and easy to use, making it suitable for developers who need quick currency formatting without a steep learning curve. Its API is simple and intuitive, allowing for rapid integration.
