$rootScope is the top-most scope in AngularJS apps and is shared among all components. $scope binds a view to a controller's model and functions. Scopes are hierarchical, with $rootScope at the top and all other scopes as its children. The example demonstrates defining values on $rootScope and $scope, and how they can be accessed within and outside controllers depending on the scope.

Understanding AngularJS $rootScope and $scope
Scope is an object that refers to the application model. it acts as glue between controller and view.
Scopes are hierarchical in nature and follow the DOM (Document Object Model) structure of your
angular app.
AngularJS has two scope objects: $rootScope and $scope.
$scope
A $scope is a JavaScript object which is used for communication between controller and view. Basically,
$scope binds a view (DOM element) to the view model and functions defined in a controller.
$rootScope
The $rootScope is the top-most scope. An app can have only one $rootScope which will be shared
among all the components of an app. Hence it acts like a global variable. All other $scopes are children
of the $rootScope.
AngularJS: $rootScope and $scope with example
external.js
//defining module
var app = angular.module('IG', []);
//the run function acts as a main method for the angular app.
app.run(function ($rootScope) {
$rootScope.site = "interviewgully.com";
$rootScope.name = "Brajesh Kumar"
});
app.controller("myController", function ($scope, $rootScope) {
$scope.name = "Sujeet Srivastava";
$scope.welcome = "Welcome to " + $rootScope.site;
});
app.controller("testController", function ($scope, $rootScope) {
$scope.welcome = "Welcome to " + $rootScope.site;
});

How it works
1. When you use ng-model with $rootScope objects then AngularJS updates those objects under a
specific $scope of a controller but not at global level $rootScope.
2. Create a private $scope for each controller to bind it to the view.

The document discusses directives in AngularJS. It begins with an overview of HTML elements, nodes, tags and attributes. It then defines what a directive is - code that enhances HTML elements with additional functionality. Directives are defined using the .directive() method and can customize element behavior. The document covers different types of directives like isolating directive scope for reusability. It provides examples of creating a basic directive that passes data into its template using attributes, and binding to isolate scope properties.

Shaping up with angular JSBrajesh Yadav

The document provides an overview of AngularJS, including what it is, how it works, and how it differs from other frameworks. Some key points: - AngularJS is an open-source JavaScript framework for building single-page apps. It uses MVC architecture and handles tasks like routing, data binding and dependency injection. - It augments HTML to give it native MVC capabilities. This allows developers to encapsulate portions of a page as AngularJS apps rather than forcing the entire page to be Angular. - AngularJS makes apps more responsive by updating parts of a page without refreshing, as opposed to traditional pages that refresh entirely.

Controller in AngularJSBrajesh Yadav

The document outlines the role of controllers in AngularJS, describing how they define application behavior by managing the scope while avoiding DOM manipulation and input/output formatting. It also illustrates the controller hierarchy for property access across parent and child controllers, as well as methods for sharing data through services. Best practices for naming controllers and examples of AngularJS applications are provided.

AngularJS IntroductionBrajesh Yadav

The document presents an agenda for an introduction to Angular JS. It discusses what should be known before using Angular JS, including HTML, CSS, JavaScript concepts. It explains how web pages get to browsers through DNS servers. It defines Angular JS as a client-side framework written in JavaScript that allows extending HTML with custom tags and attributes. It contrasts Angular JS's MVC approach of augmenting HTML with other frameworks manipulating the DOM from outside. The benefits of Angular JS are listed as MVC support, two-way data binding, enabling single page apps, managing state, controls, parallel development and handling dependencies. The agenda concludes with a roadmap and directory architecture for Angular JS.

multiple views and routingBrajesh Yadav

UI routing in AngularJS allows defining application states and nested views. Key steps include: 1. Include the angular-ui-router.js file and inject the ui.router module. 2. Configure states using $stateProvider and child states for nested views. 3. Link to states with ui-sref and display views with ui-view. States define the URL, template, and controller for sections of the app. Child states enable nested views within a state. The example app defines routes for two users with nested lists.

AngularJS ScopesMohamed Elkhodary

AngularJS scopes provide an execution context for expressions and allow for communication between controllers and views. Scopes are arranged hierarchically and mimic the DOM structure, with child scopes prototypically inheriting from parent scopes. Directives like ng-repeat and ng-controller create new child scopes, while others like ng-include use the parent scope. Scopes are created, register watchers, observe mutations during digest cycles, and are destroyed when no longer needed to clean up memory.

Its silent and within the JP Culture/Area/Training/Word of Mouth. It allows remote healing but there’s limits for practitioners and masters. We are not allowed to share certain secrets/tools. Some content is designed only for “Masters”. Some yoga are similar like the Kriya Yoga-Church (Vowed Lessons). We will review both Reiki and Yoga (Master symbols) later on. Sounds Simple but these things host Energy Power/Protection. Imagine This package will be a supplement or upgrade for professional Reiki. You can create any style you need. ♥♥♥ •* ́ ̈ ̧.• (Job) Tech for students: In short, high speed is essential. (Space, External Drives, virtual clouds) Fast devices and desktops are important.

Its now collapsing. This means anything lower, darker realms, astral, and matrix are below 5D. 5D is thee trend. It’s our New Dimensional plane. However; this plane takes work ethic, integration, and self discovery. ♥♥♥ •* ́ ̈ ̧.• We don’t need to slave, mule, or work double shifts to fuse Reiki lol. It should blend naturally within our lifestyles. Same with Yoga. There’s no need to use all the poses/asanas. For under a decade, my fav exercises are not asanas but Pilates. It’s all about Yoga-meditation when using Reiki. (Breaking old myths.) Thank You for reading our Orientation Sampler. The Workshop is 14 pages on introduction. These are a joy and effortless to produce/make.

Sustainable Innovation with Immersive LearningLeonel Morgado

Prof. Leonel and Prof. Dennis approached educational uses, practices, and strategies of using immersion as a lens to interpret, design, and planning educational activities in a sustainable way. Rather than one-off gimmicks, the intent is to enable instructors (and institutions) to be able to include them in their regular activities, including the ability to evaluate and redesign them. Immersion as a phenomenon enables interpreting pedagogical activities in a learning-agnostic way: you take a stance on the learning theory to follow, and leverage immersion to envision and guide your practice.

Battle of Bookworms 2025 - U25 Literature Quiz by Pragya Pragya - UEM Kolkata Quiz Club

Battle of Bookworms is a literature quiz organized by Pragya, UEM Kolkata, as part of their cultural fest Ecstasia. Curated by quizmasters Drisana Bhattacharyya, Argha Saha, and Aniket Adhikari, the quiz was a dynamic mix of classical literature, modern writing, mythology, regional texts, and experimental literary forms. It began with a 20-question prelim round where ‘star questions’ played a key tie-breaking role. The top 8 teams moved into advanced rounds, where they faced audio-visual challenges, pounce/bounce formats, immunity tokens, and theme-based risk-reward questions. From Orwell and Hemingway to Tagore and Sarala Das, the quiz traversed a global and Indian literary landscape. Unique rounds explored slipstream fiction, constrained writing, adaptations, and true crime literature. It included signature IDs, character identifications, and open-pounce selections. Questions were crafted to test contextual understanding, narrative knowledge, and authorial intent, making the quiz both intellectually rewarding and culturally rich. Battle of Bookworms proved literature quizzes can be insightful, creative, and deeply enjoyable for all.

Understanding angular js $rootscope and $scope

1. InterviewGully.com Understanding AngularJS $rootScope and $scope Scope is an object that refers to the application model. it acts as glue between controller and view. Scopes are hierarchical in nature and follow the DOM (Document Object Model) structure of your angular app. AngularJS has two scope objects: $rootScope and $scope. $scope A $scope is a JavaScript object which is used for communication between controller and view. Basically, $scope binds a view (DOM element) to the view model and functions defined in a controller. $rootScope The $rootScope is the top-most scope. An app can have only one $rootScope which will be shared among all the components of an app. Hence it acts like a global variable. All other $scopes are children of the $rootScope. AngularJS: $rootScope and $scope with example external.js //defining module var app = angular.module('IG', []); //the run function acts as a main method for the angular app. app.run(function ($rootScope) { $rootScope.site = "interviewgully.com"; $rootScope.name = "Brajesh Kumar" }); app.controller("myController", function ($scope, $rootScope) { $scope.name = "Sujeet Srivastava"; $scope.welcome = "Welcome to " + $rootScope.site; }); app.controller("testController", function ($scope, $rootScope) { $scope.welcome = "Welcome to " + $rootScope.site; });

2. InterviewGully.com index.html <!DOCTYPE html> <html ng-app="IG"> <head> <title>AngularJS rootScope and scope :: InterviewGully.com</title> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.js"></script> <script src="Scripts/external.js"></script> </head> <body> <div ng-controller="myController"> <h1>rootScopeController</h1> <p>rootScope: {{site}}</p>  <p>rootScope(ng-model): <input type="text" ng-model="site" /></p> <p>welcome from scope: {{welcome}}</p> <p>welcome from scope(ng-model): <input type="text" ng-model="welcome" /></p> <p>scope: {{name}}</p> </div> <div ng-controller="testController"> <h1>ScopeController</h1> <p>rootScope: {{site}}</p>  <p>rootScope(ng-model): <input type="text" ng-model="site" /></p> <p>welcome from scope: {{welcome}}</p> <p>name from rootScope: {{name}}</p> </div> <div> <h1>Outside from both Controller</h1> <p>name from rootScope: {{name}}</p> <p>site from rootScope: {{site}}</p> </div> </body> </html>

3. InterviewGully.com How it works 1. When you use ng-model with $rootScope objects then AngularJS updates those objects under a specific $scope of a controller but not at global level $rootScope. 2. Create a private $scope for each controller to bind it to the view.
