Angular Signals Reactive
Angular 16+ introduced signals: lightweight, synchronous reactive state. Instead of observables, use signal() to create state, computed() for derived state, and effect() for side effects. Signals are simpler than RxJS for most use cases, faster, and more intuitive. Master signals and you're at the forefront of Angular's evolution. Career path: Angular engineer → full-stack engineer building modern reactive systems. Salaries: $110k-190k (junior to senior), growing.
什麼是 Angular Signals Reactive
Angular Signals (introduced Angular 16, stable Angular 17) are fine-grained reactive state management. Create state with signal(), derive state with computed(), and trigger side effects with effect(). All synchronous, no observables required. Signals simplify Angular's reactive model. Instead of observables (powerful but complex), you get simple, reactive primitives similar to Vue 3 or SolidJS.
