Boris Cherny, author of Programming TypeScript, explains how TypeScript can scale JavaScript projects to larger teams, larger code bases, and across devices. Topics include: gradual typing, type refinement, structural typing, and interoperability...

Fred Schott stops by to talk about TypeScript, what DX means in 2023, a bit of GripeScript, and being transparent about what Astro is good at, and what it's not.

Dave's about to be eclipsed, the state of TypeScript in 2024, signals stage zero proposal, corrections on accessibility in frameworks (thanks!), web apps for better collaborative writing, getting productivity sniped, the problem with email may be you, indieweb follow up, and ultimate guitar tab apps.

Dave & Chris and thoughts on career advice that worked 3 years ago but isn't as helpful now, marking tests with ChatGPT, is taking a Drupal job in 2024 a good idea, Chris got #gear sniped, P3 color follow up, the confusing File System APIs, and where did all the lightboxes go?

The goal: Let everyone play with many different TypeScript features and get an overview of TypeScript capabilities and principles.

In this episode, Charles is at Microsoft Connect 2017 in NYC. Charles speaks with Amanda Silver. Amanda is deemed the  TypeScript and future of JavaScript guru, and this year's speakers at Microsoft Connect with Visual Studio Live Share. Amanda shares what is new with TypeScript and how that is a kind of subscript to JavaScript.

Episode Summary

In this episode of JavaScript Jabber, Joe Eames and AJ O’Neal talk about what TypeScript is, and their background and experiences with it. They discuss the different kinds of typed languages such as dynamic vs static, strong vs weak, implicit vs explicit casting and the reasons for selecting one type over the other. AJ shares his opinion on not preferring TypeScript in general, while Joe offers a counter perspective on liking it, and both give a number of reasons to support each argument. They talk about some final good and bad points about TypeScript and move on to picks.
