CCATP #465 – Bart Busschots Programming By Stealth 25 – Case Study of a JavaScript API

PBS_Logo.pngBart gave me another two weeks to get my homework done on Programming By Stealth and brings us a case study of how to create a JavaScript API on Github. He uses a real life example of a small, open source library he released over the weekend called barfificer.linkTookit.js. This library includes many of the bits and pieces we’ve been working on in Programming By Stealth, how to add a rel of no opener on all links with a target of _blank (the ones that open in a new tab) and adding a little icon in the url to politely tell the reader that you’ll be navigating away from the page you’re on. It’s a great lesson in the structure of how Github works and even more importantly how it automatically creates beautiful documentation from Markdown comments in the code.

CCATP #461 Bart Busschots Programming By Stealth 24 – Creating a JavaScript API

PBS_Logo.pngIn this week’s installment of Programming By Stealth, Bart teaches us how to create a JavaScript API up to and including an easy way to create professional documentation in order to publish our work as a JavaScript library. In order to get there we learn how to write reusable and sharable code, how “closures” help you keep your variables out of the global scope so they don’t mess up other people’s code, we learn one Ternary Operator), and my favorite, self-executing anonymous functions.

Apologies for getting the episode number wrong in the audio – I said it was #460 when it’s actually #461.

CCATP #459 Bart Busschots Programming By Stealth 23 – Creating Elements with jQuery

PBS_Logo.pngIn this installment of Programming By Stealth, we’re working towards our first truly practical assignment in the series – a function that finds all links on a page, and if, and only if, they lead to an external page, alters them to open in a new tab, and appends an icon indicating that fact. Bart’s amazing full on tutorial is over at bartbusschots.ie/…. I also mention a fun little jQuery Easter egg, which you can find at citymapper.com. Just follow the link and open the console on your favorite browser and you’ll find a text based adventure game!

CCATP #457 Bart Busschots Programming By Stealth 22 – jQuery Events

PBS_Logo.pngBart Busschots joins us again for his continuing series called Programming By Stealth. In this episode Bart explains how to embed JavaScript into a webpage, how to control when JavaScript executes and then teaches us about the browser event model. Using this model he teaches us how we can change things on a web page when the user clicks or after a defined length of time, or at time intervals. It’s our first time outside of the sandbox so it’s great fun to manipulate web pages and have them do our bidding! Bart’s full tutorial is at: bartbusschots.ie/… and it includes some downloadable files that are very useful for following along.

CCATP #455 Bart Busschots Programming By Stealth 21 – jQuery Basics

PBS_Logo.pngIn this installment of Programming By Stealth, Bart Busschots continues our baby steps into jQuery, keeping us inside the JavaScript console. He reviews some html and css basics and then teaches us how to select elements with jQuery, limit the search, and filter the results. Then he shows us how to start changing the css using jQuery, even including function chaining I interrupt him with a lot of questions (as always) but it’s a terrific episode that was really fun.

CCATP #451 Programming By Stealth – Solving JavaScript Challenges Part 2

In episode #449, Bart Busschots walked us through how he’d solve the first half of the JavaScript challenges from PBS 19. This week we finish the second half of the 5th problem about Complex Numbers. Just like the last episode, we’re giving you the audio in the podcast, but if you’d like to watch the video of Bart building the solutions, you can watch right here.

CCATP #449 Programming By Stealth – Solving JavaScript Challenges

In this week’s episode of Chit Chat Across the Pond, Bart Busschots starts walking us through the JavaScript challenges he gave us on Programming By Stealth 19. Bart got this crazy idea that we should do this episode as a video so that he could walk through each challenge from scratch on a blank canvas. He builds up the solutions and explains each step while I ask him questions. It was our first time recording video so we’re pretty excited that it actually worked. Thanks to Steve for the intro video that incorporates Bart’s Programming By Stealth logo into the Chit Chat Across the Pond logo that Terry Austin made for us!

CodeCademy + PBS to Learn JavaScript

Codecademy+pbsBart Busschots has been working on a series in Chit Chat Across the Pond entitled Programming By Stealth, and we just finished episode 18. These lessons started with HTML, then moved into CSS, and since episode 12 we’ve been learning JavaScript. Bart has written terrific tutorials with excellent explanations of the terminology, logic and process of coding in JavaScript. The foundation he is laying is adaptable to learning other languages as well.

A few lessons back I suggested an enhancement to the series. At the risk of being labeled as teacher’s pet, I asked him to assign homework to us, or as he likes to call them, challenges. He came up with the challenges, but they’ve been really hard for me. Continue reading “CodeCademy + PBS to Learn JavaScript”

CCATP #446 – Programming by Stealth – 18 of x JavaScript Miscellany

In this episode of Programming By Stealth, Bart Busschots takes us through the final stages of learning JavaScript within the playground. Now that we know about objects, we need to re-visit the arguments object present in every JavaScript function. We need to take a detailed look at the typeof operator, and we need to look at some built-in objects and functions JavaScript provides. We also need to look at how JavaScript handles regular expressions, and finally, we need to introduce the concept of exception handling. Bart’s full written tutorial is available at bartbusschots.ie/….

During this episode we briefly mention a wonderful email from Jill about factorials and more. I wanted to include the full letter in the shownotes here because it contains some wonderful explanations, especially an even better explanation of strongly vs. weakly-typed languages. Here’s Jill’s entire letter:

Hi, me again

I think there’s a concept you haven’t quite grasped in PBS, and that’s types. I know you’ve mostly got it, but I think perhaps I might be able to help unconfuse you on a few edge cases.

CCATP #444 – Programming by Stealth – 17 of x JavaScript Objects

In this continuing series with Bart Busschots, we get a more detailed look at objects, and then we look at some standard functions and objects that are built into JavaScript. We also take a proper look at two operators we’ve seen before, typeof and instanceof. Bart’s full written tutorial is available at bartbusschots.ie/….
