DojoDojo is a JavaScript framework targeting the many needs of large-scale client-side web development. This circumvents the need to actively manipulate the DOM and encourages bootstrapping and rapid prototyping of web applications. Likewise, any alterations to the view are reflected in the model. The $scope service in Angular detects changes to the model section and modifies HTML expressions in the view via a controller. Instead, templates are rendered in plain HTML according to data contained in a scope defined in the model.
Hello !zngularJS directives allow the developer to specify custom and reusable HTML tags that moderate the behaviour of certain elements.Notable Angular directives:ng-app - Declares an element as a root element of the application allowing behaviour to be modified through custom HTML tags.ng-bind - Automatically changes the text of a HTML element to the value of a given expression.ng-model - Similar to ng-bind, but allows two-way data binding between the view and the scope.ng-class - Allows class attributes to be dynamically loaded.ng-controller - Specifies a JavaScript controller class that evaluates HTML expressions.ng-repeat - Instantiate an element once per item from a collection.ng-show& ng-hide - Conditionally show or hide an element, depending on the value of a boolean expression.ng-switch - Conditionally instantiate one template from a set of choices, depending on the value of a selection expression.ng-view - The base directive responsible for handling routes that resolve JSON before rendering templates driven by specified controllers.ng-if - Basic if statement directive which allow to show the following element if the conditions are true.AngularJS' two-way data binding is its most notable feature and reduces the amount of code written by relieving the server backend from templating responsibilities.
