If you’re a JavaScript developer, chances are, you’ve heard about TypeScript. In this talk, I want to share an alternative approach to incrementally enable type-checking without all the tooling.

JSDocs allows you to introduce type-checking into your project bit-by-bit as it makes sense. You can stick to working within JavaScript projects, or adopt TypeScript syntax when and where it makes sense for you and your team.

I break it into four stages:
Enabling type-checking in a JavaScript file
Enabling type-checking in a whole JavaScript project
Integrating type-checking into CI/CD Pipeline
Generating type definitions for Open-Source Libraries
