Vue.js is designed to be incrementally adoptable, making it extremely versatile. This means that you can easily integrate Vue into other projects or use it alongside other libraries. Its modular architecture allows developers to pick and choose which libraries they want to use, be it for routing, state management, or HTTP requests.
Moreover, Vue's component-based structure is encapsulated, ensuring minimal conflict with other code in a project. Vue also provides wrappers or integrations for several popular libraries and tools, ensuring smoother interoperability. So, whether you're looking to sprinkle a bit of reactivity into an existing project or use Vue in tandem with another library, it's flexible enough to accommodate your needs.
