Question: What is Angular change detection?

Answer: Change detection in Angular is the process of checking for changes in the application's state and updating the DOM accordingly. Angular uses a mechanism called Zone.js to intercept asynchronous operations and trigger change detection.

Example:

ngDoCheck() {
  // Custom change detection logic
}
