DOM is the document object model that is utilized for executing dynamic changes. It is used for enhancing the speed of JS frameworks.
.ng-disabled Directive: It binds AngularJS application data to the disabled attribute of HTML elements.
.ng-show Directive: It displays the HTML element.
More directives are available apart from the above. It executes any work indirectly through abstractions, TemplateRef, and viewContainerRef.
The process of reactJS uses the lightweight copy of real DOM; therefore, the execution of reactJS is dependent on virtual DOM. To check the redrawn nodes, the React-based application compares the two DOM treemaps: the first is a real DOM tree, and the second is a virtual DOM tree.
After that, it functions the operation only on those nodes which need any changes. Thus, improving the performance of the software. But in complicated apps such as animation and complex synchronization, react.js may fail.
AngularJS depends on a two-way data binding process, making a visitor for every binding to change any track in the DOM. If there are many visitors, it can get slow as the developer makes any transformation, then the visitor needs to change it again.
The digest loop compares the new value against the initial value when any view is updated. Following that, the watcher calculates the actual value. Therefore, your application will perform better since the watcher tracks any changes in the view model, so you no longer have to go back to the previous application.
This framework was designed according to developer convenience. It uses the MVW architecture, separating the application logic from the given representation to the user interface. It provides a modular solution that can operate simultaneously. Therefore, this framework is beneficial for productive team interaction.
Model-View-Controller, Model-View-View-View-Model, and Model-View-Whatever structures do not exist in this library. Therefore, multiple developers cannot work on the same code simultaneously because the logic and representation are not separated. And, a lot of time is involved in developing any application. As a result, most developers dislike the complicated development process.
