How to create a signal in Angular?

AngularJunior~1 min read

A signal is created using the signal() function from @angular/core. It takes an initial value. Example:

import { signal } from '@angular/core';

const counter = signal(0);

Now counter() is used to read the value, while set() or update() are used to change it:

counter();          // get the value
counter.set(5);     // set a new value
counter.update(v => v + 1); // change based on the previous one
