React is a library created and maintained by Facebook and is open-source, meaning developers can freely use and modify the code. It has become popular due to its simplicity and performance, making it an attractive choice for web developers.
When it comes to Netflix, the answer to whether it is written in React or not is a bit complicated. Netflix does not natively use React, but it does use React Native for its mobile applications. React Native is a version of React that is optimized for mobile devices, but it is not the same as React.
The advantages of using React for Netflix are that it makes it easier to create a more interactive user interface and allows developers to quickly build and deploy applications. On the other hand, there are some disadvantages to using React, such as it not being optimized for streaming services and not being the most efficient way to handle large amounts of data.
Overall, it is difficult to say if Netflix is written in React or not. While React has some advantages, it may not be the most efficient way to create a streaming service.
