Scope variable not updating inside ng-repeat
The issue of scope variables not updating inside an ng-repeat in AngularJS typically occurs when AngularJS is unable to detect changes made to the model within the context of the….
$apply already in progress
The error $apply already in progress in AngularJS occurs when you attempt to manually trigger a $digest cycle using $scope.$apply() while AngularJS is already in the middle of running a….
[$rootScope:infdig] Infinite digest cycle detected
The error [$rootScope:infdig] Infinite digest cycle detected in AngularJS occurs when the AngularJS $digest cycle goes into an infinite loop. This happens when Angular’s change detection mechanism continuously re-evaluates the….
How to profile an AngularJS application for performance issues
Profiling an AngularJS application is crucial for identifying and resolving performance issues, especially as the application grows in size and complexity. The goal is to pinpoint slow components, inefficient digest….
Using immutable data structures with AngularJS
AngularJS relies on two-way data binding, meaning that changes in the model automatically update the view and vice versa. However, frequent modifications to objects and arrays can lead to performance….
Preventing $digest cycle from triggering on every event
In AngularJS, the $digest cycle is responsible for detecting changes and updating the DOM accordingly. However, frequent triggering of the $digest cycle (especially on high-frequency events like mousemove, scroll, and….
One-time binding (::) to improve performance
In AngularJS, two-way data binding continuously monitors model variables for changes. This can lead to performance issues when dealing with large datasets or complex applications. To optimize performance, AngularJS provides….
What is the $digest cycle in AngularJS?
In AngularJS, the $digest cycle is the mechanism responsible for detecting changes in the application and updating the UI accordingly. It is part of AngularJS’s two-way data binding, ensuring that….
Preventing unnecessary re-renders in directives
When working with custom directives in AngularJS, performance can suffer due to unnecessary re-renders caused by excessive $digest cycle executions. Preventing these re-renders is crucial for optimizing application performance. 1…..
