What is vue.js?
Vue.js (pronounced /vjuː/, like “view”) is an open-source, progressive JavaScript framework for building user interfaces and single-page applications. It is lightweight and easy to learn, making it a popular choice for developers of all levels.
What is top use cases of vue.js?
Here are some key features of Vue.js:

- Reactive: Vue.js uses a reactive data model, which means that changes to the data are automatically reflected in the UI without the need for manual DOM manipulation.
- Composable: Vue.js components are reusable and self-contained, making it easy to build large and complex applications.
- Virtual DOM: Vue.js uses a virtual DOM to efficiently update the UI, resulting in high performance.
- Easy to learn: Vue.js has a simple API and a large community of developers. This makes it easy to learn and get started with.

How vue.js Works & Architecture?
Vue.js is a JavaScript framework for building user interfaces. It is based on the Model-View-ViewModel (MVVM) pattern, which separates the data (Model), the user interface (View), and the glue that binds them together (ViewModel).
Here’s a breakdown of how Vue.js works and its architecture:
- Model: The Model represents the data of your application.
It can be a simple JavaScript object or a more complex data structure.
Any changes to the Model are automatically reflected in the View. - View: The View is the user interface of your application.
It is typically written in HTML, but can also be written in other languages like JSX.
The View uses data bindings to connect to the Model. - ViewModel: The ViewModel is the glue that binds the Model and the View together.
It is a Vue.js instance that contains the data, logic, and methods for your component.
The ViewModel reacts to changes in the Model and updates the View accordingly.
Model:
- The Model represents the data of your application.
- It can be a simple JavaScript object or a more complex data structure.
- Any changes to the Model are automatically reflected in the View.
View:
- The View is the user interface of your application.
- It is typically written in HTML, but can also be written in other languages like JSX.
- The View uses data bindings to connect to the Model.
ViewModel:
- The ViewModel is the glue that binds the Model and the View together.
- It is a Vue.js instance that contains the data, logic, and methods for your component.
- The ViewModel reacts to changes in the Model and updates the View accordingly.

Step by Step Tutorials for vue.js for hello world program
A basic “Hello World” program in Vue.js involves the following steps:
Step 1: Include Vue.js in your HTML file (as mentioned in the installation step).
Step 2: Create a Vue instance and specify the target element to bind it with:
var app = new Vue({
el: '#app',
});
Step 3: Create a template containing your desired output:
<div id="app">
<p>Hello World!</p>
</div>
Step 4: View the result in your HTML file:
<!DOCTYPE html>
<html>
<head>
<title>Vue.js Hello World</title>
<script src="path/to/vue.js"></script>
</head>
<body>
<div id="app">
<p>Hello World!</p>
</div>
<script>
var app = new Vue({
el: '#app',
});
</script>
</body>
</html>
You can then preview the HTML file in a browser, and it should display “Hello World!”.
