VueJS is created by Evan You, an ex-worker from Google. The primary version of VueJS was released in Feb 2014. It as of late has timed to 64,828 stars on GitHub, making it exceptionally famous.

Features of Vue Js:

• Virtual DOM
  
  VueJS utilizes virtual DOM, which is likewise utilized by different frameworks, for example, React, Ember, and so forth. The progressions are not made to the DOM, rather a reproduction of the DOM is made which is available as JavaScript data structures. At whatever point any progressions are to be made, they are made to the JavaScript data structures and the last is contrasted and the first data structure. The last changes are then refreshed to the genuine DOM, which the client will see evolving. This is acceptable as far as advancement, it is more affordable and the progressions can be made at a quicker rate.

• Data Binding:
  
  The data binding feature helps manipulate or assign values to HTML attributes, change the style, assign classes with the help of a binding directive called v-bind available with VueJS.

• Components
  
  Components are one of the important features of VueJS that helps create custom elements, which can be reused in HTML.

  v-on is the attribute added to the DOM elements to listen to the events in VueJS.

• Animation/Transition
  
  VueJS provides different approaches to apply the change to HTML components when they are included/refreshed or expelled from the DOM. VueJS has a worked experiencing significant change segment that should be folded over the component for progress impact. We can without much of a stretch include outsider activity libraries and furthermore add greater intuitiveness to the interface.

• Computed Properties
  
  This is one of the important features of VueJS. It helps to listen to the changes made to the UI elements and performs the necessary calculations. There is no need for additional coding for this.

• Templates
  
  VueJS gives HTML-based layouts that quandary the DOM with the Vue occurrence data. Vue aggregates the layouts into virtual DOM Render capacities. We can utilize the format of the render capacities and to do so we need to supplant the layout with the render work.

• Directives
  
  VueJS has built-in directives such as v-if, v-else, v-show, v-on, v-bind, and v-model, which are used to perform various actions on the frontend.

• Watchers
  
  Watchers are applied to data that changes. For example, form input elements. Here, we don’t have to add any additional events. Watcher takes care of handling any data changes making the code simple and fast.

• Routing
  
  Navigation between pages is performed with the help of a vue-router.

• Lightweight
  
  VueJS script is very lightweight and the performance is also very fast.

• Vue-CLI
  
  VueJS can be installed at the command line using the vue-cli command-line interface. It helps to build and compile the project easily using vue-cli.

Vue Js Comparison with other Frameworks

1. VueJs V/S React

Virtual DOM

Virtual DOM is a virtual portrayal of the DOM tree. With virtual DOM, a JavaScript object is made which is equivalent to the genuine DOM. Whenever a change should be made to the DOM, another JavaScript object is made and the progressions are made. Afterward, both the JavaScript objects are analyzed and the last changes are refreshed in the genuine DOM.

VueJS and React both utilize virtual DOM, which makes it faster.

Template v/s JSX

VueJS utilizes HTML, Js, and CSS independently. It is simple for an amateur to comprehend and receive the VueJS style. The layout based methodology for VueJS is exceptionally simple.

Respond utilizes jsx approach. Everything is JavaScript for ReactJS. HTML and CSS are all pieces of JavaScript.

Installation Tools

React uses create react app and VueJS uses vue-cli /CDN/npm. Both are very easy to use and the project is set up with all the basic requirements. React needs webpack for the build, whereas VueJS does not. We can start with VueJS coding anywhere in jsfiddle or codepen using the CDN library.

Popularity

Respond is well known than VueJS. The opening for work with React is more than VueJS. There is a major name behind React for example Facebook which makes it increasingly famous. Since React utilizes the center idea of JavaScript, it utilizes the best act of JavaScript. One who works with React will be generally excellent with all the JavaScript ideas.

VueJS is a creating framework. By and by, the openings for work with VueJS are less in contrast with React.

VueJS has taken the great parts from Angular and React and has assembled an incredible library. VueJS is a lot quicker in contrast with React/Angular due to its lightweight library.

2. VueJS v/s Angular

Similarities

VueJS has a lot of similarities with Angular. Directives such as v-if, v-for are almost similar to ngIf, ngFor of Angular. They both have a command-line interface for project installation and to build it. VueJS uses Vue-cli and Angular uses angular-cli. Both offer two-way data binding, server-side rendering, etc.

Complexity

Vuejs is anything but difficult to learn and begin with. As examined before, a novice can take the CDN library of VueJS and begin in codepen and jsfiddle.

For Angular, we have to experience a progression of steps for the establishment and it is minimal hard for fledglings to begin with Angular. It utilizes TypeScript for coding which is hard for individuals originating from center JavaScript foundation. Be that as it may, it is simpler to learn for clients having a place with Java and C# foundation.

Popularity

At present, Angular is more popular than VueJS. A lot of organizations use Angular, making it very popular. Job opportunities are also more for candidates experienced in Angular. However, VueJS is taking up the place in the market and can be considered as a good competitor for Angular and React.

Dependencies

Angular provides a lot of built-in features. We have to import the required modules and get started with it, for example, @angular/animations, @angular/form.

VueJS does not have all the built-in features as Angular and needs to depend on third-party libraries to work on it.

Flexibility

VueJS can be easily merged with any other big project without any issues. Angular will not be that easy to start working with any other existing project.

Backward Compatibility

We had AngularJS, Angular2, and now Angular4. AngularJS and Angular2 have immense contrast. Undertaking application created in AngularJS can't be changed over to Angular2 due to the center contrasts.

The ongoing adaptation of VueJS is 2.0 and it is acceptable within reverse similarity. It gives great documentation, which is exceptionally straightforward.
