Should I choose ReactJS or AngularJS for web app development?

Both technologies are ideal for front-end development. Both are great for building rich apps. When it comes to data binding, ReactJS works one way, while AngularJS works both ways. AngularJS creates a real DOM while ReactJS creates a virtual DOM.

The biggest difference is in state management. Angular comes with data binding, whereas today React is usually complemented by Redux to provide unidirectional data flow and work with immutable data.

For less experienced developers, ReactJS might be a safer option due to its relative simplicity. However, AngularJS development offers a complete solution for front-end development that could benefit large projects.

If you are building a project with a lot of modules, Angular is a better option as it makes project management much easier. The Angular code will be very easy to understand and also easy to modify. But Angular is a bit slower than ReactJS. In 2021, React ranked first and Angular third in the list of most wanted frameworks.
