Angular Signals

This lesson is part of Angular · All levels

Summary

Signals are a feature of modern Angular reactivity in the form of state values that track its changes. Made with signal(), values are read with parentheses and changed by set() or update(). Computed generates derivative values, whereas effect runs automatic logic as its dependencies change.

Key points

Signal() makes the container of reactive value
Read values using parentheses such as count()
Set() changes the value and update() changes based on the old value
Computed() and effect() react to signal changes
