Currency to number transformation in JavaScript

Dealing with monetary values of different currencies is undoubtedly a big challenge, especially when you don't know the type of currency you will need to deal with. This is why currency-to-float was created, a tiny JavaScript library.

With this, you can easily transform currency strings into numeric values regardless of the currency format. It is a versatile tool that simplifies your financial and web development projects.

Example

Here's how straightforward it is to use currency-to-float:

import currencyToFloat from 'currency-to-float';

// Sample array of expenses in USD
const expenses = ['$12.50 USD', '$8.75 USD', '$20 USD', '$15.25 USD'];

// Sum the expenses
const totalExpense = expenses.reduce(
  (acc, expense) => acc + currencyToFloat(expense),
  0
);

console.log(totalExpense); // Output: 56.5

In this example, we have an array of expenses in US dollars. By leveraging currencyToFloat function, we convert each expense string to a numeric value and calculate the total using the reduce function.
