Bart continues his redux and new information by circling back through Objects as Arrays in JavaScript. I don’t know about you, but I get a lot out of the redux episodes because it cements in place concepts that were a bit wiggly before he goes through it again. The one new concept he goes through is Array Destructuring which sounds ominous and destructive but which allows us to dive into arrays and create new and more interesting arrays.
Bart also debuts a new way he’s providing the content for the lesson. If you still want to download the zip file with all of the example files, you can, but you can also view the source code and view the HTML in a browser with a Github link. By the way, the zip file is now living on a content delivery network. This is important to note if you’re coming in from Safari with the more recent security updates because it will prompt you to agree to downloads from this new URL.
Bart’s fabulous tutorial show notes (including the links to the source for this week’s episode) are available at pbs.bartificer.net/…
XPath, and by extension XQuery, are a couple of languages where arrays begin from 1 instead of 0. These are programming languages for manipulating XML documents and databases.
