Special Guest - Sarah Dayan In this episode of JavaScript Jabber, the panelists talk to Sarah Dayan, who is a Frontend Software Engineer working for Algolia in Paris. They about the complications in handling money in software development and ask Sarah about the journey that led to the creation of Dinero.js, it’s implementation details, importance of maintaining good documentation, dealing with issues faced along the way, various features of Dinero and working with open source projects in general. Check it out!Show Topics:0.40 - Advertisement : https://www.netlify.com/ 1:44 - Sarah introduces herself and Chris talks about his interest in learning more about Dinero and compliments Sarah on its great documentation.3.10 - Sarah gives some background saying that she created and published Dinero around a year ago. She goes on to explain that the Dinero library helps in handling monetary values. It comes with several methods to parse, manipulate and format these values. The reason behind creating it is that there is no consensus on representing money in software development currently. She shares the story from her previous job where her work was to maintain legacy accounting software, and along the way they realized, that since JavaScript did not have a way to natively represent decimal values, it led to adding large numbers of rounded up numbers continuously, eventually leading to wrong computations.6:50 - Aimee asks about ways to handle different currencies in Dinero. Sarah answers that she has followed Martin Fowler’s money pattern where two different currencies were not allowed to be worked on directly, conversion was mandatory, just like in real life.7:50 - Charles talks about his old freelance work where he was overwhelmed while handling and representing money in software.8:25 - Aimee enquires if Dinero can be used for both frontend and backend. Sarah replies that it can be used anywhere and explains that there is no such thing as just a number when it comes to money, there must be a currency associated with it.9:30 - Charles asks how to figure out the direction to go to when dealing with money and to make sure that all use-cases are covered. Sarah answers that in cases such as floating-point math where the computations don’t end up being accurate as handling is not supported, numbers can be used if treated as subunits (for e.g. 100cents = 1$). However, even then, there are issues in dividing money. She then explains the procedure of “allocation” from the Fowler pattern and she says that Dinero helps in doing the same in such scenarios.12:54 - They discuss how they did not realize how difficult it was dealing with monetary values in development. Sarah talks about the fact that there are numerous aspects involved in it, giving the example of rounding off and stating that there are even factors such as different laws in different countries that need to be considered.16:00 - AJ asks details about crafting the library, maintaining the centralized code and covering of edge cases and using inheritance. Sarah explains the concept of domain driven development and the importance of being an expert in the respective domains. She talks about the library structure briefly, describing that is kept very simple with a module pattern and it has allowed her to manage visibility, make it immutable, include currency converters, formatters and so on.19:34 - AJ asks about the internal complexity of the implementation. Sarah answers that code wise it is extremely simple and easy, anyone with a limited JavaScript experience can understand it.20:50 - AJ asks if it’s open source to which Sarah answers in affirmative and says that she would like external help with implementing some features too.22:10 - Chris asks about Sarah’s excellent documentation approach, how has she managed to do it in a very detailed manner and how important it is in an open source project. Sarah says that she believes that documentation is extremely important, and not having good docs is a big hindrance to developers and to anyone who is trying to learn in general. She talks about her love for writing which explains the presence of annotations and examples in the source code.27:50 - Charles discusses how autogenerated documentation gives an explanation about the methods and functions in the code but there is no guidance as such, so it is important to have guides. Sarah agrees by saying that searching for exact solutions is much simpler with it, leading to saving time as well.29:43 - Chris speaks about Vue also being quite good at having guides and links and thanks Sarah for her work on Dinero.30:15 - Advertisement - https://sentry.io/welcome/ - Use code “devchat” to get two months free on Sentry’s small plan.31:23 - Chris asks what the process is, for creating and running Dinero in different places. Sarah explains that she uses rollup.js which is a bundler suited for libraries, it takes in the ES module library and gives the output in any format. She states that the reason for using the ES module library is that she wanted to provide several builds for several environments with a clean and simple source and goes on to explain that these modules are native, have a terse syntax, easy to read and can be statically analyzed. She also gives the disadvantages in choosing webpack over rollup.36:05 - Charles asks if anyone else is using Dinero. Sarah replies that around two or three people are using it, not much, but she is happy that it is out there to help people and she enjoyed working on it.37:50 - Joe asks if there are any interesting stories about issues such as involving weird currency. Sarah answers in affirmative and gives the example of the method “hasCents”. She explains that she had to deprecate it because the unit “cents” does not have any value in non-Western currencies, and has created “hasSubUnits” method instead. She explains some problems like dealing with currencies that don’t support the ISO 4217 standard.42:30 - Joe asks if social and political upheavals that affect the currencies have any effect on the library too. Sarah gives the example of Chinese and Japanese currencies where there are no sub-units and states that it is important to be flexible in developing stuff in an ever-changing domain like money. She also says that she does not include any third-party dependency in the library.46:00 - AJ says that BigInts have arrived in JavaScript but there is no way to convert between typed arrays, hexadecimal or other storage formats. But later (1:10:55), he corrects that statement saying that BigInts in fact, does have support for hexadecimals. Sarah talks about wanting to keep the code simple and keep developer experience great.49:08 - Charles asks about the features in Dinero. Sarah elaborates on wanting to work more on detecting currencies, improve the way it is built, provide better support for type libraries and get much better at documentation.52:32 - Charles says that it is good that Sarah is thinking about adopting Dinero to fit people’s needs and requirements and asks about different forms of outreach. Sarah says that she blogs a lot, is active on Twitter and attends conferences as well. Her goal is not popularity per se but to help people and keep on improving the product.55:47 - Chris talks about the flip side that as the product grows and becomes popular, the number of support requests increases too. Sarah agrees that open source projects tend to eat up a lot of time and that doing such projects comes with a lot of responsibility but can also help in getting jobs.59:47 - Sarah says that she is available online on her blog - https://frontstuff.io/, on Twitter as Sarah Dayan and on GitHub as sarahdayan.1:00:06 - Advertisement - https://clubhouse.io/ 1:01:01 - Picks!1:11:42 - END - Advertisement - https://www.cachefly.com/ Picks:Sarah

That would be a no. I’m Charles Max Wood from Devchat.tv. And this week, we’re going to be talking about Sweet.js.Before we get started, there is one thing I want to announce really quickly and that is that we have scheduled a Book Club episode for January 10th and that’s going to be with David Herman who wrote ‘Effective JavaScript’. So it’s a pretty slim book, should be easy to get through. But yeah, if you want to follow along with that discussion, then by all means, join in.Alright. Let’s talk about Sweet.js. Has anyone…AJ:  Can you hear me now?CHUCK:  Yeah.AJ:  Okay, cool.CHUCK:  So, I went and looked at it. I fiddled with it a little bit. I didn’t have enough time to really get into it the way that I wanted to. It looks really cool though. What kind of gave you the idea of doing something like macros for JavaScript, Tim?TIM D:  Well, I guess it’s just something I’ve sort of wanted for JavaScript for awhile. But the main sort of impetus I guess was, I was interning at Mozilla Research this past summer. And Dave Herman who has worked on macros in the past basically said he thought that it was sort of finally possible to do for JavaScript. And so, that was a possible sort of intern project for the summer. And so, that’s what got it started.JAMISON:  So can you back up and talk about what macros are, because I’m sure there are lots of people that don’t know and lots of people that hear macros and think like CP process are macros.TIM D:  Right yeah, exactly. So, C style macros are the sort of painful and sort of limited. The macros that Sweet.js implements are much more in line with sort of scheme style macros. So,Special Guest: Tim Disney.

I live in Columbus, Ohio. About a year ago, me and a guy named Todd Kaufman started a new company called Test Double. Previously, he and I had been doing consulting for a long, long time. And we’re up to eight people now. And we have a good time building software with an emphasis on terrific interaction design which has resulted in us kind of developing a specialty for well-crafted frontend code, predominantly JavaScript. And I imagine that’s probably why I’m here today.CHUCK:  Awesome. Alright. Well, we brought you on to talk about Jasmine. Jasmine was written by, was it Pivotal Labs? JUSTIN:  Yeah, Pivotal Labs guys. A guy names Christian Williams who I think has since moved on to Square, and D.W. Frank who’s still at Pivotal. They wrote the core library and me and a whole bunch of other people in the community have piled on with different runners and add-ons and extensions in the sort of like little ecosystem of the 25 people who write unit tests for JavaScript.CHUCK:  All 25 of you, huh?JUSTIN:  Well, it’s not a lot, right? It’s been a fun journey of being one of the very few people who really, really got excited or chose to get excited about making it easier for folks to write tests in JavaScript or as easy as it would be for whatever servers and language they’d be using.Special Guest: Justin Searls.

This week on our panel we have Jamison Dance.JAMISON: Hi guys!CHUCK: Tim Caswell.TIM: Hello!CHUCK: And AJ O’Neal. And I'm Charles Max Wood from devchat.tv. This week, we are going to be talking about ‘Node-webkit’. It seems like Tim is the most familiar with it, so why don’t you jump in and tell us a little bit about it?TIM: All right. Basically the idea is to make desktop apps using Node and then having HTML as your display layer for your widgets. And I start a project doing this several years ago from Topcube, but I failed miserably because I'm not that good of a C engineer. And since then, a few projects have taken up the idea. Node-webkit is one done by Intel and the main engineer there is Roger Wang. So on Roger Wang’s GitHub there is node-webkit. And the other popular one is called ‘app.js’ and I think there is a couple others as well. And some other people have taken over my Topcube project and they use it for some maps app. And all these projects had the basic idea of you have a desktop native app that has Node and node-webkit inside of it.CHUCK: So, is it kind of like PhoneGap or some of these other things for mobile?TIM: Yeah. It’s similar to PhoneGap in that, you get more privileges than a browser would have in a more native experience. Instead of just the PhoneGap extensions, you get all of Node -- you get the full Node environment -- which means you can use all that existing libraries and ecosystem.JAMISON: So how does this compare to the Chrome native apps thing? Because I know that they are more --- already have some like JS APIs that let you touch stuff on the server or things like that. Is this just – it’s not sandbox at all?TIM: Yeah. I mean, this is a native app. It’s not in your browser at all. It bundles its own webkit.JAMISON: Oooh.TIM: It’s more like -- what was that flash thing they had years ago?AJ: ‘Adobe Air’?TIM: Air yeah. It’s like Adobe Air that doesn’t suck.

Chuck is at a conference this week. So, he is not here. We have with us Joe Eames.JOE: Hey everybody!JAMISON: Tim Caswell.TIM: Hello.JAMISON: And we have two special guests. I'm going to mangle your names, so I'm sorry. It’s Misko Hevery.MISKO: Misko Hevery. Yeah, thank you.JAMISON: Misko Hevery and Igor Minar?IGOR: Minar. Yeah.JAMISON: Great. You guys wanna introduce yourself really quick?MISKO: Sure. So, this is Misko Hevery, original creator of Angular.js.IGOR: Hi everybody! I'm Igor. I joined Misko about 2 years ago on this venture of creating better browser and better environment for creating client-side applications.JAMISON: And if you can’t tell, we are going to talk about Angular.js this week. So, I know it is kind of a Google project now. Did it start out that way?MISKO: It started out with something I was working on and eventually I've open sourced it at a product with Google internal application and just gotten such a rave reviews and new features that people actually says, “Hey why don’t you work on this full time and turn in on to a real product?” So, that's how it’s started.JAMISON: Oh, wow. So, there’s actually a team in Google who are working on Angular as their job?MISKO: Yeah.IGOR: Yes.JAMISON: That's awesome.IGOR: It’s just two of us here now, but we have a bunch of other people working full time on Angular.js and also main contributors--JAMISON: Oh, go ahead sorry.IGOR: There is a team behind Angular.js.JAMISON: Do you think you can give an overview and kind of a comparison to contrast Angular to some of the other MVC frameworks that people like before you? I mean, Backbone I guess is what most people know.  So, what makes Angular different from Backbone? How does it work?MISKO: So, I have never used Backbone besides it’s framework. But, my understanding is that Backbone is basically you have declare model and then launch on changes on its mode. And the way it does so is that there is a model class object. And whenever you modify the models that use special getters and setters methods, the Backbone know about the changes. So, this is pretty different from Angular because we don’t require you to inherit from anything. We have special getters and setters. Basically, any JavaScript object can be a model. So, that’s one big difference.JAMISON: But you can still observe the changes on objects like that?MISKO: Right.Special Guests: Igor Minar and Miško Hevery.
