React was developed by Facebook. Angular was developed by Google. Both are known to be the largest technology giants across the globe. But which frontend framework makes the cut? We put an end to the React vs Angular debate through an overview of key differences.
Angular is a framework while React is a library. Angular as a framework is more structured compared to React. While React leaves the developers with plenty of choices, Angular as a framework is more constrained. Experienced developers may prefer a library since it enables flexibility. Integrating libraries with an existing code-base is far easier when compared to integrating an entire framework.
Performance–wise, is a well-known fact that the DOM calls are expensive and time-consuming compared to other operations since they require going through the vast HTML document structure. React minimizes the number of DOM calls by using a concept called “Virtual DOM”. Virtual DOMs are faster and therefore, at times, the performance observed in the case of React is better.
React provides uni-directional data binding. Angular, alternatively, provides both unidirectional and bi-directional data binding. In Angular, the data and the User Interface (UI) are coupled more tightly – changing one, changes the other – that’s why it is bi-directional.
In React, the coupling isn’t that tight. Bi-directional data binding complicates the process of debugging the application. React’s one-way data flow, on the other hand, makes it easy to comprehend what the code actually does and to find and fix bugs.
When it comes to writing and debugging code, Angular is quite challenging. Where as with React, code can be reused and since it is a standalone library, debugging is fairly easy. There is no better framework. Both are updated continuously to keep up with the competitor. It all comes down to personal preference.
