Bringing Types to Ember with Chris Krycho

In early 2017, Chris Krycho was working at one of the few startups using Ember, searching for a way to bring types to the emerging language. His primary goal became solving semantic versioning for TS. As Chris kept iterating, striving to combine multiple programming worlds, other engineers joined him in the pursuit until eventually, the Ember TypeScript Core team was born. 

Today, Chris is a lead engineer at LinkedIn, a father, husband, runner, music composer, and whiskey enthusiast. His current goal is to ensure Ember Polaris has first-class TypeScript support. Aside from offering new dad advice to Robbie, Chris also describes what can become a superpower for new developers willing to work.

In this episode, Chris talks with Chuck and Robbie about best-case uses for TypeScript, a defense of complicated library code, Chris’ ultimate goal with software engineering, and his advice for programmers on the rise.

[16:27] - “TypeScript support is pretty essential to modern web development. Even if you’re not using TypeScript in your web app, you are using TypeScript because under the hood, all of the tooling that exists across the ecosystem, more or less, uses TypeScript.” ~ @chriskrycho

[19:39] - “There’s no project in which TypeScript is necessary. There are very few projects in which it might not be useful, but that’s going to depend on your team, your coding style, your mental frame, your background, etc.” ~ @chriskrycho

[60:45] - “Getting deep on subject matter as well as having a general breadth is a really powerful one-two punch in terms of being able to grow as an engineer, to actually understand what you’re working on.” ~ @chriskrycho
