## Prerequisites
- You need a connection to the XRP Ledger network. As shown in this tutorial, you can use public servers for testing.
- You should be familiar with the Getting Started instructions for your preferred client library. This page provides examples for the following:
- **JavaScript** with the [xrpl.js library](https://github.com/XRPLF/xrpl.js/). See [Get Started Using JavaScript](get-started-using-javascript.html) for setup steps.
- **Python** with the [`xrpl-py` library](https://xrpl-py.readthedocs.io/). See [Get Started using Python](get-started-using-python.html) for setup steps.
- You can also read along and use the interactive steps in your browser without any setup.

This page provides JavaScript examples that use the [xrpl.js](https://js.xrpl.org/) library. See [Get Started Using JavaScript](get-started-using-javascript.html) for setup instructions.
Since JavaScript works in the web browser, you can read along and use the interactive steps without any setup.

**Note:** The JavaScript code samples in this tutorial use the [`async`/`await` pattern](https://javascript.info/async-await). Since `await` needs to be used from within an `async` function, the remaining code samples are written to continue inside the `main()` function started here. You can also use Promise methods `.then()` and `.catch()` instead of `async`/`await` if you prefer.
