Introducing Signals: Angular’s New Primitive for Reactivity
Reactivity is a fundamental concept in front-end development, enabling dynamic user interfaces and smooth user experiences. Angular, one of the most popular front-end frameworks, has recently introduced a new primitive for reactivity: Signals. Signals are a lightweight, high-performance mechanism for achieving reactivity in Angular applications. What are Signals? Signals are a new primitive for reactivity in Angular. Unlike other primitives such as Observables or Promises, Signals are simple and lightweight. They enable efficient data binding in Angular applications without adding unnecessary complexity or overhead. In Angular, Signals are created using the @Output decorator, which is used to define an event that can be emitted by a component. When the event occurs, the Signal is emitted with a value that can be consumed by other components or services in the application. Here's an example of how a Signal can be defined in an Angular component: import { Component, Output, EventEmit...
