PBS 88 of X — DOM & jQuery Objects Redux Dec 14, 2019

Show notes

Bart is nearing the end of his mini-series recapping al of the different hats JavaScript objects wear, doing a lot of redux to cement the concepts that have been spread over so many lessons. He takes a really interesting approach this week to his teaching. He explains a concept and then instead of having a contrived example, he shows us exactly how that concept works in action in his homework solution from PBS 85. His solution to the homework assignment is, of course, beautiful and elegant. Beautiful he gives credit to Bootstrap, elegant he would probably give credit to jQuery.

I am really enjoying these redux segments because they cement things that were still wobbly, or perhaps even gone from my memory. Each time through I'm finding I understand how to even categorize the information in my brain. I explained to Bart that I think he's actually changing the way my brain is wired now.

PBS 87 of X — JavaScript Iterators Objects & Generator Functions Nov 30, 2019

Show notes

I'm not going to lie, this episode of Programming By Stealth with Bart Busschots was a bit head bendy. Bart explains JavaScript Iterator Objects and Generator functions but without his excellent examples I'm certain I would never have been able to get the concepts to even slightly congeal in my brain. Iterator Objects and Generator functions are some of the joys of ES6 and have great value.

That value is demonstrated in the succinctness of the code Bart writes for us to create a Fibonacci series in a beautiful web form. That work, by the way, is a bonus challenge if you're done with your homework from the previous episodes. As you listen along, if you hear us yelling "spoiler alert" and making alarming noises, that's when Bart's solution to the challenge is about to be described. It's a rare instance where I actually let you have one chapter mark in Programming By Stealth so you'll be able to jump back to the solution after you're done with your own solution.

PBS 85 of X — Objects as Arrays in JavaScript (Redux & Update) Nov 03, 2019

Show notes

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.

PBS 84 of X – Objects as Dictionaries in JavaScript (Redux & Update) Oct 20, 2019

Show notes

Bart has been noticing that there are a few key features in JavaScript that haven't ever really congealed for me and is circling back in hopes of firming them up. The other reason he's going over these topics is that new options have been created since we first covered them. The first of these subjects is objects as dictionaries. I confessed to him recently that I've never successfully done a for loop on my own yet, so we slow down a bit during that part but we speed up again into what are actually more challenging topics. We had a lot of fun doing this episode (even when I was stuck!)

At the end of the show I suggested a palate cleanser, which is a feature of his Security Bits segment he does for the NosillaCast. I found an awesome tweet by developer Sarah Dresner (@sarah_edo: "Apparently the only cure for jetlag is to make SVG animations of farting rhinos with the new @greensock API 💨". Of course I had to follow that link, and it was awesome. It is literally an SVG file of an adorable little rhino trotting along and tooting. After Bart and I got off the air we took advantage of the fact that she'd posted the farting rhino on codepen.io so we view the html, css and JavaScript to see how she did it. I know this is silly but that's what makes it so awesome.

PBS 83 of X Bootstrap Cards Oct 04, 2019

Show notes

Bart finishes up our first exploration of Bootstrap 4 with a look at one its most versatile components, the so-called Card. This is one of those components that’s so generic it’s hard to describe, but once you learn about it you’ll start seeing it all over the web. Cards really are ubiquitous!

It’s important to stress that while we’re wrapping up our exploration of Bootstrap 4 with this installment, that does not mean we’ve come close to covering every feature this impressive library offers. Instead, the aim was to cover the big-picture items, and leave you with enough experience to be able to learn the rest independently by reading Bootstrap’s excellent documentation.

PBS 82 of X – Async & Await Sep 20, 2019

Show notes

We're back after a summer hiatus (where Bart was working too hard) with a new installment where we attempt to dust off Allison's brain and learn about two new promise-related keywords, async and await. Both of these keywords were actually added to the core JavaScript language, so this doesn't happen that often.

With async and await, we can actually get away from doing promise chains and create much more readable code while still being able to control parallel and in series tasks. Bart had to drag me along a bit in this one but I saw the beauty of it when we were done.

Bart's fabulous tutorial shownotes can be found at PBS 82 of X — Async & Await : Bart Busschots.

PBS 81 – The JavaScript Promise Utilities Jul 12, 2019

Show notes

In this installment of Programming By Stealth, Bart teaches us how to use Promises, with a capital P to get promises when we already know the value we want to supply. That sounds funny but it will make sense in context. Then he shows us how we can control parallelization of promises using Promise.all(). It's a very sensible lesson, and not brain bendy at all. (I really like those.)

PBS Supplemental — Dorothy Rendon on the PBS Index Jun 25, 2019

Show notes

In the very first Programming By Stealth supplemental episode, Allison interviews Dorothy Rendon, the programmer behind the PBS Index. If you haven't seen it before, it's an index that Dorothy has created for the Programming By Stealth students to helpt them find key topics in Bart Busschots's fabulous tutorial shownotes.

PBS 80 — JavaScript Promise Chains Jun 14, 2019

Show notes

Bart Busschots (successfully) explains the concept of JavaScript promise chains. It's a rough ride because of the subject itself, but he gets us there through his care and detail in explaining the concepts and of course his great examples. When he's done, you'll know how to chain promises together, you'll understand what data is passed through, and you'll understand why he says, "Don't have unhandled rejections, it's just not nice."

PBS 79 — Introducing JavaScript Promises May 31, 2019

Show notes

Bart has been _promising_ us Promises for ages now and he finally fulfills his promise by explaining thenables. Promises are a tool to get us out of "callback hell", which we experienced a while back. I think he made us suffer through that so we'd appreciate Promises. In this episode he shows us the beauty and elegance of the concept but leaves us wanting more. Bart spent a lot of time trying to get the shownotes and his narrative to take this rather abstract concept and make it concrete, and I think he did a grand job of it.
