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.

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/….

CCATP #442 – Programming by Stealth – 16 of x JavaScript Callbacks

PBS LogoIn this installment of Programming By Stealth, Bart Busschots takes our understanding of functions to the next level. The techniques we encounter today would be considered advanced techniques in most other languages, and you could spend years developing in Java and never encounter an anonymous function. However, because of how JavaScript is integrated into HTML documents, these techniques are considered fundamental in JavaScript, and anonymous functions are a dime a dozen! Before we delve into anonymous functions, we’ll start by taking a deeper look at how JavaScript deals with function arguments.

CCATP #438 – Programming by Stealth – 14 of x JavaScript Loops & Arrays

PBS LogoWe’re back to Programming By Stealth with Bart Busschots where he explains how to create Arrays in Javascript and how to use “while” and “for” to create loops to access the information in Arrays. It’s a little bit of a propeller beanie episode but we powered through till I got it!

CCATP #434 – Programming by Stealth – 13 of x (JavaScript Conditionals)

In this week’s episode of the continuing series with Bart Busschots, he introduces the concept of conditionals. We’ll learn whether boogers is true or false, how Javascript handles text strings and numbers in comparisons (what’s bigger or smaller), how equality is really three different things, and we’ll learn about logical operators like AND, OR and NOT to be used in conditional statements. Bart has updated the Javascript Playground he created so be sure to grab the new version.

CCATP #432 – Programming by Stealth – 12 of x (JavaScript Intro)

PBS LogoIn this installment of Programming By Stealth, Bart Busschots dips our baby toe into Javascript. We learn the very basic building blocks, including how to make statements, how to make comments, three rules for variables, the difference between strings and numbers and what you can do with them, operators and concatenation. With the exception of the modulus section, I understood everything he said! Learn why this episode ends with the line, “Find out next week if boogers is true or false!” Find Bart’s detailed tutorial at bartbusschots.ie/… including a link to his JavaScript Playground.
