What is Angular? Angular is a web framework that empowers developers to build fast, reliable applications. What are signals? A signal is a wrapper around a value that notifies interested consumers when that value changes. Signals can contain any value, from simple primitives to complex data structures. You read a signal's value by calling its getter function, which allows Angular to track where the signal is used. Signals may be either writable or read-only.   Writable signals Writable signals provide an API for updating their values directly. You create writable signals by calling the signal function with the signal's initial value: const count = signal(0); // Signals are getter functions - calling them reads their value. console.log('The count is: ' + count()); To change the value of a writable signal, either .set() it directly: count.set(3);   or use the .update() operation to compute a new value from the previous one: // Increment the count by 1. count.update(value ...
