Angular Signals Improve Change Detection And Performance
Angular Signals available from v16, providing change notifications for improved performance and reactivity. Use signals with computed() or effect(), or untracked() to read values without triggering reactive functions.
Angular Signals are available for developers from Angular v16. Signals provide a new way for developers to tell our templates (and other code) that our data has changed. We can think of a signal as a value plus a change notification. A signal is just a particular type of variable that holds a value. However, unlike other variables, a signal is notified when the variable value changes. This improves Angular's change detection, improving performance and making our code more reactive. We can track signals using the computed() or effect() function. However, sometimes we want to read a signal value...
