Web / ReactJS Interview questions
How is React different from Angular?
| Criteria | React | Angular |
| Learning Curve | Angular has its own learning curve but comparitively easy . | React has steep learning curve as it doesn't include routing library and need onboarding of state management libraries ilke Redux/MobX. |
| Ease of development and Productivity | The Angular CLI eases development experience. | The use of third-party libraries affects the speed of React development and productivity. |
| Performance | Angular uses real DOM for its applications which makes the apps using Angular slower. | React uses a virtual DOM and is best suited for pages that need regular content updates. The size of the library is small too, which makes it more lightweight and dynamic. |
| Data Binding | The Angular framework uses a two-way binding approach that changes the model state automatically when any change is made in the UI element and vice versa. | The React library uses a one-way approach that allows the change in the UI elements only after a change is made in the model state. |
| Regular DOM vs Virtual DOM | Angular uses real DOM, so the whole tree structure is refreshed when a single change is made. This makes the process slower. | React uses a Virtual DOM, which allows the developers to make changes to the tree without the need to update the entire tree. |
| Flexibility and Performance | Angular does not provide the flexibility that React does. | React provides the developers with a lot of tools, libraries, and varying architecture to choose from. |
