Is this for you?
Problem: Job posts want TypeScript. Your brain still thinks in plain JS, so every ts file feels like friction.
Agitate: Copy-pasting fixes from Stack Overflow doesn’t build judgment—you stay slow in code review and when AI output breaks types.
Solve: You learn by editing real code in the screencast, seeing compiler feedback inline, and shipping a small typed project you can explain in an interview.

FreeTypeScript fundamentals, typing React and Express, and a hands-on typed project—all in interactive scrims.

TypeScript rewards a tight feedback loop. Passive video hides the moment the compiler “clicks.” In Scrims you change a type, see the squiggle, fix it—same rhythm as work (and easier than reconciling AI snippets with your tsconfig).
Module breakdown

|---|---|---|
| TypeScript Fundamentals | 2.1 hrs | 30 |

Pros and cons
| Pros | Cons |
|---|---|
| Free, structured path | Not a replacement for the full TS handbook |
| React + Express slices | Advanced generics depth is limited by runtime |
| Interactive, not passive | You still need real repo practice afterward |
Learning paths
