Features of VueJS

Virtual DOM

  • A virtual representation of the DOM is called virtual DOM.
  • A JavaScript object that is identical to the real DOM is constructed using virtual DOM. 
  • Every time a modification to the DOM is required, a new JavaScript object is formed, and the modifications are made. Later, the final changes are updated in the actual DOM after comparing the two JavaScript objects.

Data Binding

  • In VueJS, data binding comes with a binding directive called v-bind.
  • The data binding functionality assists in manipulating or assigning values to HTML attributes, changing the style, and assigning classes.


  • Components are independent elements with their own data logic and view.
  • One of VueJS's key features, components, enables the creation of unique elements that can be reused throughout HTML.

Event Handling

  • To listen to the events in VueJS, the DOM elements have a property called v-on.

Transition / Animation

  • When HTML elements are added, changed, or removed from the DOM, VueJS offers a variety of techniques to apply the transition. 
  • For the transition effect, an element must be wrapped in the built-in transition component of VueJS. 
  • The interface can be more interactive, and third-party animation libraries are simple to add.

Computing Properties

  • One of VueJS's key characteristics is its computing properties. 
  • Paying attention to the UI element changes and making appropriate calculations is beneficial. 
  • No further coding is required for this.


  • It provides HTML-based templates that connect the data from the Vue.js instance to the DOM. 
  • The templates are converted into simulated DOM Render functions. 
  • The template for render functions can be used by web developers, who can then swap out the template for the render function.


  • The built-in directives in VueJS can be used to carry out a variety of front-end tasks, including v-if, v-else, v-show, v-on, v-bind, and v-model.
