How come? Angular is Typescipt first so typing guarantees are builin.
Not in templates.
You need to use the Angular Language Service extension for vs code, it works perfectly giving you full type completion and error checking in templates https://github.com/angular/vscode-ng-language-service
Though I use Angular in my day-to-day, I would really love to be in React land for that reason alone. I've had too many interface bugs due to simple template typos
