How to use the locale function from numeral

numeral.locale is a function in the Numeral.js library that sets the locale settings for formatting and displaying numbers according to a specific language or culture.

How does numeral.locale work?

The numeral.locale function is a part of the Numeral.js library, which is a JavaScript library that provides a simple way to format and manipulate numbers. When you call the numeral.locale function, you pass in an options object that defines the locale settings for formatting and displaying numbers. These settings include the decimal separator, the thousands separator, the currency symbol, and more. The locale settings are defined based on a specific language or culture, such as "en-US" for English in the United States, "fr-FR" for French in France, and so on. Numeral.js provides built-in locale definitions for many different languages and cultures, which you can use directly or modify as needed. Once you have defined the locale settings, you can use them to format and display numbers using the numeral function. For example, you can format a number as a currency value in the current locale using the numeral(number).format('$0,0.00') method. Overall, the numeral.locale function provides a powerful way to format and display numbers according to a specific language or culture in a web application using the Numeral.js library.

const numeral = require("numeral");

// Define the locale settings for French in France
numeral.locale("fr-FR", {
  delimiters: {
    thousands: " ",
    decimal: ",",
  },
  abbreviations: {
    thousand: "k",
    million: "m",
    billion: "b",
    trillion: "t",
  },
  currency: {
    symbol: "€",
  },
});

// Use the locale to format and display numbers
const number = 1234567.89;
const formatted = numeral(number).format("$0,0.00");
console.log(formatted); // Output: €1 234 567,89

In this example, we first require the numeral module in our Node.js application. We then use the numeral.locale function to define the locale settings for French in France. We specify that the thousands separator should be a space and the decimal separator should be a comma, and we define abbreviations for large numbers (thousand, million, etc.) and the currency symbol as the euro symbol. We then use the numeral function to format a number as a currency value using the locale settings. We pass in the number 1234567.89 to the numeral function and use the format method to format the number as a currency value with a euro symbol and two decimal places. Finally, we print the formatted value to the console using the console.log method. Overall, this example demonstrates how to use numeral.locale to set the locale settings for formatting and displaying numbers in a web application using the Numeral.js library.
