Two-way data binding
One-way data binding
Manages dependencies automatically
Requires additional tools to manage dependencies
Best for SPA’s that update single view at a time
Best for SPA’s that update many views at a time
We have further discussed their individual differences with respect to componentization, performance, data binding, directives, and templates.
Angular has a fixed structure and it is based on the three layers that are Model, View, and Controller. The Model is initialized by the controller, which is then transformed into HTML to create View for the users.
The advantage in Angular’s performance is the feature of two- way data binding whereas React utilizes a virtual Document Object Model, which is considered as an advantage of React in comparison with other frameworks including Angular. However, the performance of an application may vary depending on the size of the application and code optimization.
The Data binding concept is considered as major difference between Angular and React. Angular web development uses Two-way data binding which means that any change in the UI field would also change the data in the model dynamically. In case of React web development, it uses one-way data binding, where the data in the application flows in a single direction. Angular is efficient as developers find it easy to work with whereas React is more towards the structural representation, understandability because the data flows in a single direction
Directives and Templates
Angular Directives are used to organize the code around DOM. Developers can access the directives only through DOM. Developers can also create their own directives other than the standard directives (ng-bind, ng-app) that are available.
React does not distinguish between templates and directives, template logic should be written in the template itself. This approach of template and logic being placed in one place is better as we would spend lesser time in understanding.
Angular and React are different instruments that work great for single-page applications in their individual ways. Some developers may prefer angular after considering the reasons to choose angular and some may prefer react. However the decision would be with respect to the project requirements.
