Why is DI central to Angular architecture versus Vue's module system?
Tests architectural grasp of inversion of control. Angular DI enables hierarchical injectors, tree-shakable providers, and runtime substitution without direct imports unlike Vue modules. Red flag: calling DI mere convenience or claiming Vue matches Angular DI.
Tests deep architectural understanding of inversion of control and framework-level service boundaries. A strong answer notes Angular DI uses hierarchical injectors for scoped lifetimes, tree-shakable providers via providedIn, and runtime substitution without changing consumer code. Contrast Vue's explicit module imports where sharing logic means direct file coupling and no built-in scope isolation. Red flag: dismissing DI as syntactic sugar or claiming Vue Composition API replicates Angular's full injector tree by default.
