144: Gary Bernhardt - TypeScript and Testing

In this episode of Fullstack Radio, I talked to Gary Bernhardt about building execute program as a full stack TypeScript application and the implications using TypeScript has on what you need to test. This is Fullstack Radio episode one forty four. Hey, everyone. Welcome to another episode of the Fullstack Radio podcast. I'm your host, Adam Whelan. And today, it's my pleasure to welcome to the show, Gary Bernhardt, who I've been a massive fan of since I basically first became a professional programmer way back in, like, 2012. So it's super awesome to have you on the show, Gary. How's it going, man? It's going well, and thank you for having me. And I you had never told me that, so I'm very flattered. Yeah. Yeah. I was, like, a huge, like, Destroy All Software fan from, like, back in the you know, in my early days of learning, to program. And I think still to this day, like, I haven't seen, like, an educational resource that really, like, resonated with what the stuff that I wanted to learn as as much as Destroy All Software did. So, I actually remember seeing you speak at CodeMash, and, I was, like, too nervous to even, like, introduce myself because I was, like, such a fanboy at the time in my my early junior days of programming. So, yeah, it's awesome to have a chance to chat with with you here. Yeah. Well, yeah, I appreciate it. So where do you wanna start? Yeah. So I think what I wanna talk about today is I mean, what originally got me excited to talk to you in terms of topics is you recently I don't know if recently is really the right word anymore, but something that you're currently kind of your active project is execute program, which is like an online, tool to help people, like, learn different programming topics with all this, like, crazy innovative, like, interactive learning tech that you've sort of, like, built to make this experience sort of really unique and and work better than a lot of the ways that people have historically tried to learn these sorts of topics. And while you've been doing that, occasionally, you'll tweet out, like, pretty interesting little tidbits around how you've been, like, sort of putting it together. And the thing that sort of got it on my radar originally was just realizing that you were building this whole thing as, like, a full stack JavaScript application or TypeScript application, I think. Right? Yeah. And, until then, I knew you as, like, the Ruby and Python guy. You know what I mean? And Mhmm. With Bash and all and Vim and, you know, all this other stuff. But definitely not known for, like, in in the in the sort of JavaScript world. So it got me kinda interested because I was thinking, well, okay. Well, why is Gary, like, going full, JavaScript? He's, like, building stuff with Node and …
