You will need a machine that is capable of running Node.js. We will discuss how to install this in the first chapter--you can run it on pretty much anything, but having a few extra gigabytes of RAM available will probably help you while developing. Some of the mapping examples later in the book are kind of CPU intensive, though most machines produced since 2014 should be able to handle it.
You should also have the latest version of your favorite web browser--mine is Chrome, and I use it in the examples, but Firefox also works well. You can also try to work in Safari or Internet Explorer/Edge, or Opera, or any number of other browsers, but I find Chrome's developer tools to be the best.
