Since the source code is hosted on the GitHub repository, there is a lot of support and documents available for Three.js. Here are the docs . React is easy to understand and uses the JS library to build user interfaces for web applications (front-view or model of MVC architecture). React is maintained by Facebook and a few other companies. React is declarative, efficient, and flexible enough to let developers build more complex UIs using the existing pieces of code, also known as components. React is fast and scalable, hence any changes to applications do not need a page to reload. Here's a guide with the best React courses currently available . Vue js is based on the Virtual DOM model, much like React, and has a component-based architecture. Using templates of Vue.js, apps can be created faster. Vue also requires fewer lines of code for the same task that would need more code with other libraries. If you need a small application to be built in less time, Vue should be your perfect choice. By combining Vue with other tools and utilities, you can get a full-fledged framework. As a framework, Vue can handle complex functionalities like routing, build tooling, and state management.
