Binding

  • What is the difference between one-way binding and two-way binding in AngularJS ?
    In One-Way data binding, view (UI part) not updates automatically when data model changed. We need to write custom code to make it updated every time. ng-bind has one-way data binding. While in two way binding scope variable will change it’s value every time its data model changed is assigned to a different value.
  • Explain how does AngularJS implement two-way binding?
    Data-binding in Angular apps is the automatic synchronization of data between the model and view components. The way that Angular implements data-binding lets you treat the model as the single-source-of-truth in your application. The view is a projection of the model at all times. When the model changes, the view reflects the change and vice versa.
  • What is Isolate Scope in AngularJS and why it is required?
    It is a scope that exists separately with no prototypal inheritance. It makes the components reusable and permits to control the binding either one-way or two-way.
  • Define Data Binding.
    Data binding is an automatic attunement of data between the view and model components.
  • How many types of data bindings are there in AngularJS?
    AngularJS supports both one way and two-way binding. In one way binding if we change the data model, then there will be no dynamic change that you will see in view but in two way binding, there will be a dynamic change whenever a change will be made in the data model.
  • What are the binding directives in AngularJs?
    The binding directives include: ng-bind ng-bind-html ng-bind-template ng-non-bindable ng-model
  • What are the attributes that can be used during the creation of a new AngularJs directives?
    There are several attributes that can be used during a new directive creation. They include: Template: It describes an inline template as a string. Template URL: This attribute specifies the AngularJs HTML compiler to replace the custom directive inside a template with the HTML content located inside a separate file. Replace: It replaces the current element if the condition is true if false append this directive to the current element. Transclude: It allows you to move the original children of a directive to a location inside the new template. Scope: It creates a new scope for this directive rather than inheriting the parent scope. Controller: It creates a controller which publishes an API for communicating across the directives. Require: It requires another directive to be present to function the current directive efficiently. Link: It modifies resulting in DOM element instances, adds event listeners, and set up data binding. Compile: It modifies the DOM template for features across copies of a directive, as when used in other directives. Your compile function can also return link functions to modify the resulting

Overview
