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 => value + 1);

Writable signals have the type WritableSignal.
