The answer is both yes and no. Vue.js is primarily a front-end framework, meaning it is used to create the visual elements of a website or application. It can also be used as a back-end framework, allowing it to be used to create the logic and functionality of a website or application. This means it can be considered a full-stack framework to some extent.
Vue.js is a great choice for developers who want to create powerful applications quickly. It is open-source, meaning anyone can contribute to its development, and it is well-supported by the community and has a large number of contributors. However, Vue.js is not a full-stack framework and cannot be used to create the back-end logic and functionality of a website or application.
