Decorators in Depth
summary
Decorators are shown as concrete functions that wrap or replace class members: examples include a benchmark decorator that times and logs a model method, an authenticated decorator that replaces beforeModel to redirect unauthenticated users, and Ember primitives like @tracked and @action implemented by replacing properties with getters/setters or bound functions. The talk explains stage‑one vs stage‑two spec tradeoffs, performance and tooling risks, and why relying on framework‑provided decorators is safer than authoring custom ones.
