What is Vue Js?

VueJS is an open-source dynamic JavaScript framework used to create intuitive web interfaces. It is one of the popular frameworks used to make web development simpler. VueJS focusses on the view layer. It very well can be effectively integrated into large projects for front-end development with no issues.

The installation for VueJS is very easy, to begin with. Any developer can without much of a stretch comprehend and assemble intuitive web interfaces in a short time. 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.

  • 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.

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.

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.
