TypeScript with Jake Bailey

TypeScript is a statically typed superset of JavaScript that adds optional type annotations and modern language features to improve developer productivity and code safety. The TypeScript compiler performs type checking at compile time, catching errors before code is run, and also transforms TypeScript code into clean, standards compliant JavaScript. Jake Bailey is a senior software engineer at Microsoft where he works on TypeScript and has made major contributions to the TypeScript compiler. Jake joins the podcast with Josh Goldberg to talk about TypeScript and his work. This episode is hosted by Josh Goldberg, an independent full time open source developer. Josh works on projects in the TypeScript ecosystem, most notably TypeScript eslint, the tooling that enables eslint and Prettier to run on TypeScript code. Josh is also the author of The O'Reilly Learning TypeScript book, a Microsoft MVP for developer technologies, and a live code streamer on Twitch.

I'm so excited to talk to you, Jake. We've done so much work, and you've done so much work on on TypeScript and its tooling. Everyone's useful. What is your blue sky description, your profile, say? I think my profile says, according to Git blame, I wrote the TypeScript compiler, which is, like, not true, but it is true if you don't bother to ignore all the migrations I've made. So, yes. Then I guess if you look at the new repo, then it'll probably also say something similar, but There we go. Less so. The one and only author of TypeScript? No. No. No. No. Absolutely not. I'm new, okay? Well, we're going to get into that. But before we go through all the tooling stuff you've done with TypeScript and the work on TypeScript in Go, which is incredibly exciting, let's start with you. How did you get into coding, Jake? Oh. A long time ago, I was a child in elementary school, and I had a TI73. And by some coincidence, the teacher assigned an assignment, which was basically, I want you to tell the class about a button on the calculator. And I'm pretty sure I got assigned the program button. And so I had TI Basic. And so my first language was TI Basic in like, I don't know, the third grade, fourth grade. I don't know. One of those. It's been a lot of time, obviously. And then I just it's one of those things where it's like, I kind of think I knew what I was going to do from the beginning. And I think like in middle school, I'm like, I'm going to check out the book on C, and I just learned C. And then I was like, Man, I'd really like to work on Runescape private servers so that I'm just modifying Java and trying to convince my friends to install Hamachi so …
