Angular v18 introduced an experimental feature called zoneless change detection, eliminating the need for Zone.js. This change brings faster initial renders, smaller bundle sizes, and simpler debugging.
Change detection in Angular ensures the user interface reflects real-time interactions with the app data, identifying parts that need refreshing. It maintains an up-to-date and reactive application experience.
Angular's change detection works through a component tree structure, where each component has its change detector. It iterates through the tree, checking for changes, ensuring updates occur in necessary components and children.
