TypeScript
Every chart in this course is written in TypeScript, a superset of JavaScript that adds static types. But what does that actually buy you, and why is it worth the extra syntax?
This lesson is a gentle introduction to TypeScript for dataviz: how to type your data, your component props, and your D3 scales so the compiler catches mistakes before your chart ever renders.
