TypeScript has been around for quite a while, and its popularity speaks for itself.  It has never been more important to understand how to gradually and sustainably shift to TypeScript within the existing code-base.  Today we talk with Sam Lanning, an independent software contractor in the humanitarian sector with many years of experience at GitHub and Semmle. Sam's vast experience in using TypeScript to speed up coding, eliminate debugging, and reduce technical debt helps us see the benefits of this popular programming language and foresee how to transition to it.  When you finish listening to the episode, find Sam on GitHub and connect with them on Twitter and LinkedIn.
