Vue.js Overview
Vue.js is a progressive JavaScript framework used to build user interfaces (UIs) and single page applications (SPAs). Developed and maintained by Evan You, Vue.js has gained popularity among developers due to its simplicity and flexibility. It is a lightweight framework, offers simple syntax, and comes with comprehensive documentation. Vue.js is an open-source framework, licensed under the MIT license.
Syntax
Vue.js syntax follows a data model approach, which means it uses a model to store data and bind the data to the view. The syntax for Vue.js is simple and easy to understand. It uses direct HTML templates that are compiled into reactive templates.
<div id="app">
{{ message }}
</div>
<script>
var app = new Vue({
el: '#app',
data: {
message: 'Hello World!'
}
})
</script>
In the example above, app is an instance of Vue. The el property is used to specify the element to be used for the Vue application. The data property defines the data model for the application.
Example
<!DOCTYPE html>
<html>
<head>
<title>Vue.js Example</title>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<h1>{{ message }}</h1>
</div>
<script>
var app = new Vue({
el: '#app',
data: {
message: 'Welcome to Vue.js!'
}
})
</script>
</body>
</html>
Output
The output of the above example will be a heading with the text "Welcome to Vue.js!".
Explanation
In the example above, Vue.js is included using a script tag with the source path. The el property binds the Vue instance to the #app element. The data property is used to define the message, which is then displayed in the heading of the webpage using the {{ message }} syntax. Since message is a reactive attribute of the data model, any changes in the data model are automatically reflected in the view.
Use
