What Is Vue.js?
The Vue.js is a progressive JavaScript framework and used to building the interactive user interfaces and also it’s focused on the view layer only (front end).
The Vue.js is easy to integrate with other libraries and others existing projects. Vue.js is very popular for Single Page Applications developments.
The Vue.js is lighter, smaller in size and so faster. It also supports the MVVM (Model-View-ViewModel) pattern.
The Vue.js is supporting to multiple Components and libraries like -
ü Tables and data grids
ü Notifications
ü Loader
ü Calendar
ü Display time, date and age
ü Progress Bar
ü Tooltip
ü Overlay

ü Menu
ü Charts
ü Map
ü Pdf viewer
ü And so on

ü v-show
ü v-if
ü v-for
ü v-else
ü v-on
ü v-model

<div id="demo-app">
<p v-if="IsEnable()">{{ WelcomeMsg }}</p>
</div>
VueJs Code -
var app = new Vue({
el: '#demo-app',
data: {
WelcomeMsg: 'Hello, My Name Is Anil Singh.'
},
methods: {
IsEnable: function() {
return true;
}
}
});
Result looks like - Hello, My Name Is Anil Singh.
Example 2 – VueJs 2 v-for loop -
HTML Code –
<script src="https://unpkg.com/vue"></script>
<div><h2>v-for loop</h2></div>
<div id="forLoop">
<ol>
<li v-for="user in users">
{{ user.name }} , Age - {{ user.age }}
</li>
</ol>
</div>
VueJs 2 Code –
var app = new Vue({
el: '#forLoop',
data: {
users: [
{id:1, name: 'Anil Singh', age: 32},
{id:2, name: 'Aradhya Singh' , age: 4},
{id:3, name: 'Reena Singh' , age: 25},
{id:4, name: 'Sunil', age: 27 }
