Vue.js
Vue.js is a widely-used open-source JavaScript framework for developing user interfaces and single-page applications. Based on the model-view-viewmodel (MVVM) architecture, Vue.js is an efficient tool that provides developers with the ability to create highly-responsive and interactive web applications. The framework was originally created by Evan You and is now maintained by both him and a team of active core members who continue to develop and enhance its features.
