Node.js Currency Format

To format currency in Node.js, you can use the toLocaleString() method provided by the JavaScript Number object. This method allows you to format a number according to the locale-specific conventions, including currency formatting.

Here are the steps to format currency in Node.js:

  1. Convert the number to the desired currency format using the toLocaleString() method.
  2. Specify the locale and options for currency formatting.
  3. Retrieve the formatted currency string.

Here's an example code snippet that demonstrates how to format currency in Node.js:

const number = 123456.78;
const currency = number.toLocaleString('en-US', { style: 'currency', currency: 'USD' });

console.log(currency); // Output: $123,456.78

Let's break down the code and explain each step:

  1. We define a variable number and assign it the value 123456.78. This is the number that we want to format as currency.
  2. We use the toLocaleString() method on the number variable to convert it to a currency string. The method takes two arguments: the locale and an options object.
  3. In the options object, we specify the style as 'currency' to indicate that we want to format the number as currency. We also specify the currency as 'USD' to indicate that we want to format the number as US dollars.
  4. Finally, we log the formatted currency string to the console.

You can customize the formatting by changing the locale and currency options. For example, if you want to format the number as euros, you can change the currency option to 'EUR'.

Note that the toLocaleString() method uses the system's locale settings by default. If you want to format the currency according to a specific locale, you can pass the appropriate locale code as the first argument.
