A few that come to mind: - Implementing small languages, and how it inevitably leads one to a deeper understanding of all the layers that make computing and programming possible - The Make-a-Lisp project and the language-agnostic conceptual design at the heart of it - https://github.com/kanaka/mal/blob/master/process/guide.md https://github.com/kanaka/mal/blob/master/process/guide.md - Declarative nature of React (the view as function of state); using centralized unidirectional state management and actions - Test-driven (and, similarly, type-driven) development - TypeScript - Benefits and costs of type definitions, dynamic/gradual and structural typing; power of a language integrated with the editor environment - Virtual machines, QEMU, and later Docker - Commoditized, reproducible builds for applications and their environments - Build pipeline scripts
