Explain in detail the reason for using the renderer method in Angular JS, whereas we can easily able to handle the same by using native element methods. Was there any facility for using the same? Explain.
Ans- For rendering information, Angular will presume that only one platform and browser are being used. If Angular is going to use any of the native elements of the Angular DOM, those components can only be used in the same DOM context. In Angular 6, a new class called Render2 has been introduced, which aids in the preparation of native elements such as web component elements so that they can be utilized anywhere without relying on the DOM.
