## Introduction:

Working with currency symbols can be tricky in any programming language, but especially so in Node.js. Fortunately, the `currency-symbol-map` package provides an easy-to-use solution for handling currency symbols in your Node.js application. Whether you're building a financial application or simply need to display currency symbols in your UI, `currency-symbol-map` can simplify the process for you.

## Installation:

To use `currency-symbol-map` in your Node.js application, you first need to install it via npm. Open your terminal or command prompt and run the following command:

```
npm install currency-symbol-map
```

## Usage:

Once you've installed `currency-symbol-map`, you can use it in your code like this:

```
const currencySymbolMap = require('currency-symbol-map');console.log(currencySymbolMap('USD')); // outputs '$'console.log(currencySymbolMap('EUR')); // outputs ''console.log(currencySymbolMap('JPY')); // outputs ''
```

As you can see, using `currency-symbol-map` is as simple as requiring the package and passing in a currency code as a parameter.

## Examples:

Let's take a look at some practical examples of using `currency-symbol-map` in real-world scenarios.

### Example 1: Displaying Currency Symbols in a UI

Suppose you're building an e-commerce website and need to display the currency symbol next to the product price. You can easily accomplish this with `currency-symbol-map`:

```
const currencySymbolMap = require('currency-symbol-map');const productPrice = 10.99;const currencyCode = 'USD';const currencySymbol = currencySymbolMap(currencyCode);console.log(`${currencySymbol}${productPrice}`); // outputs '$10.99'
```

### Example 2: Formatting Currency Values

In this example, we have an array of products with different currencies. We use the `forEach` method to loop through each product and get the currency symbol using the `currencySymbolMap` package. We then format the price by concatenating the currency symbol with the price rounded to 2 decimal places using the `toFixed` method. Finally, we log the name of the product and the formatted price to the console.

```
const currencySymbolMap = require('currency-symbol-map');const products = [{ name: 'Product A', price: 10.99, currencyCode: 'USD' }, { name: 'Product B', price: 9.99, currencyCode: 'EUR' }, { name: 'Product C', price: 15.99, currencyCode: 'JPY' }];products.forEach(product => { const { name, price, currencyCode } = product; const currencySymbol = currencySymbolMap(currencyCode); const formattedPrice = `${currencySymbol}${price.toFixed(2)}`; console.log(`${name}: ${formattedPrice}`);});// Output:// Product A: $10.99// Product B: 9.99// Product C: 15.99
```

## Conclusion:

The `currency-symbol-map` package provides a simple and effective way to work with currency symbols in your Node.js application. Whether you're working with financial data or simply need to display currency symbols in your UI, `currency-symbol-map` can help you streamline your development process.
