The Vue.js instance is the “ViewModel” in the MVVM (Model-View-ViewModel) architecture. It serves as the connection between the View (the HTML template) and the Model (the data). The Vue instance ties the two together, allowing you to manipulate the data in the View, and vice versa.
Example:
// Create a new Vue instance
var vm = new Vue({
el: ‘#app’,
data: {
message: ‘Hello World!’
}
})
// Access the data in the View
{{ message }}
// Update the data in the View
vm.message = ‘Goodbye World!’
