React currency text field

This question refers to a text field in React which allows users to enter values as monetary amounts. There are a couple of ways to create a React currency text field. One way is to use a library like react-number-format, which provides a customizable React component which can take input and automatically format the value as a currency amount. The code for using this library looks something like this:

 
    import NumberFormat from 'react-number-format';
    
    function App() {
      return (
        
      );
    }
  

In the code above, we are importing the NumberFormat component from the react-number-format library. Then, we create a function App which returns a NumberFormat component. The component takes the value prop (which is the value entered by the user), and additional props such as displayType, thousandSeparator, and prefix. The displayType prop is set to text, which means the component will render a text field. The thousandSeparator prop is set to true, which means that a thousands separator (such as a comma) will be used when formatting the currency amount. Finally, the prefix prop is set to $, which will display the dollar sign before the amount. Another way to create a React currency text field is to use a regular input field and to apply formatting using a library like accounting.js. The code for using this library looks something like this:


    import accounting from 'accounting';
    
    function App() {
      return (
        
      );
    }
  

In the code above, we are importing the accounting library. Then, we create a function App which returns an input field. The value of the input field is set to the result of calling the formatMoney method of the accounting library. The formatMoney method takes three parameters: the value to format, the currency symbol to use, and the number of decimal places. In this case, we are passing in the amount entered by the user, the dollar sign, and two decimal places. Both methods can be used to create a React currency text field, but they have different advantages. The react-number-format library provides more customization options, but the code is more complex. The accounting.js library is simpler to use, but there are fewer customization options.
