JavaScript fundamental (ES6 Syntax): Exercise-126 with Solution

Write a JavaScript program to create a specified currency format from a given number.

• Use Intl.NumberFormat to enable country / currency sensitive formatting.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 

// Define the 'toCurrency' function.
const toCurrency = (n, curr, languageFormat = undefined) =>
  Intl.NumberFormat(languageFormat, { style: 'currency', currency: curr }).format(n);

// Test the 'toCurrency' function with sample inputs.
console.log(toCurrency(123456.789, 'EUR')); // Output: "€123,456.79"
console.log(toCurrency(123456.789, 'USD', 'en-us')); // Output: "$123,456.79"
console.log(toCurrency(123456.789, 'USD', 'fa')); // Output: "۱۲۳٬۴۵۶٫۷۹ US$"
console.log(toCurrency(322342436423.2435, 'JPY')); // Output: "¥322,342,436,423"
console.log(toCurrency(322342436423.2435, 'JPY', 'fi')); // Output: "322 342 436 423 ¥"

Output:

€123,456.79
$123,456.79
‎$۱۲۳٬۴۵۶٫۷۹
¥322,342,436,423
322 342 436 423 ¥
