Pros of React JS
Devises Virtual DOM (Document Object Model)
Virtual DOM is used in web development to increase its efficiency and improve user experience. React JS uses the virtual version of DOM which makes the entire process even quicker and more coherent.
Uses Reusable Components
This aspect of React JS makes the working process faster as developers don't have to rewrite the components, again and again, they can reuse the old components instead.
Follows One-Direction Data Flow
React JS uses a one-direction downward data flow to bind the data which doesn't interfere with the parent structure when working with children structure.
Introduction of React Hooks
React Hooks were introduced to provide better state management as it allows state logic sharing between components and this can be done without revamping the entire code.
Cons of React JS
As React JS is an open-source library, many developers create their resources, and sometimes these resources can be made up of poor resources. Since React is developing at such a quick pace, it is hard to keep appropriate documentation.
React JS is developing at a very quick pace and some developers don't find the constantly changing libraries comfortable to work with.
Pros of Angular Programming
1. Utilizes Two-way Data Binding
Changes in data get noticed by the angular framework and then reworked in the view (DOM). It uses a data binding technique to link the data with a view. Developers can trade data from component to view and vice-versa and this establishes a two-way communication instantly.
2. Uses TypeScript
3. Modules and Directives
Module groups pipes, directives, services, and components that are associated and one module merges with other modules to create applications. Directives enable HTML extension where the developers can allocate special behaviours to DOM and thereby creating good content by using HTML.
4. Employs DI (dependency injection)
Angular uses its own DI framework and it increases the modularity and efficiency of the applications designed using the angular DI framework.
Cons of Angular Programming
1. Has too many versions
Angular is always developing which has resulted in many versions of the same. This can be puzzling for beginners who keep a track of the old versions as well.
2. Limits with SEO
It provides insufficient accessibility for search engine web crawlers as they can't see the structure of individual pages of the single-page applications.
3. Angular Framework is difficult to learn
Angular Framework has complex modules, directives, and coding languages, and understanding all this is time-taking for beginners.
4. Steep Learning Curve
Angular is a hard framework for developers to learn as its learning curve creates problems. It requires dedicated time to completely understand the framework.
