Be prepared to work through the Chapter-9 examples from GitHub at https://github.com/PacktPublishing/Hands-on-JavaScript-for-Python-Developers/tree/master/chapter-9/.
We'll be working with the developer tools in the browser, and for the purposes of illustration, the instructions and screenshots will be from Google Chrome. If you're familiar with tools in another browser, however, the concepts are similar. You may also want to have a JSON parsing extension added to Chrome if you haven't already done so.
There are no specific hardware requirements for this chapter.
