Overview Of Vue.js

Introduction

In this article, we will learn about basic concepts of Vue.js and how to install Vue.js and create a new project.

What is Vue.js

Vue.js is an open-source front-end JavaScript framework for building user interfaces and single-page applications (SPAs). Vue.js is commonly referred to as Vue and pronounced as View.

As per official Vue.js documentation,

Vue is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only and is easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

Vue was created by Evan You, who was working for Google.
