What is Vue js used for, Why vue?

Before talking about the actual use of Vue js, first, let’s discuss What is Vue JS actually about?

What is Vue JS?

Vue.js is an open-source front-end framework for developing interactive UIs and single-page applications, created by Evan You is an MVVM or Model-View-ViewModel. The first version of Vue came in the year 2014. Currently, the latest version is 3.0.2 which was released in October 2020. Vue.js is a progressive JavaScript framework for building User Interfaces. 

Vue js lets you extend HTML with HTML attributes called directives. Directives are basically instructions for VueJS to do things in a certain way. Directives in Vue.js offers functionality to HTML applications. Vue.js provides both built-in and user-defined directives. They are prefixed with -v.
Vue.js mainly focuses on view layers and can be easily integrated into big projects for front-end development. It is lightweight and also easy to learn.

Features of VueJS

Data Binding:
The data binding feature helps to assign values to HTML attributes, changing the style or assigning classes with help of a binding directive called v-bind, which lets you bind HTML attribute to JavaScript Expression.
Virtual DOM:
VueJS uses Virtual DOM like other frameworks such as React etc. The changes are not made in the Real DOM instead the virtual representation of UI is kept in memory.
Components are features of Vue that enables to create custom elements, which can be reused in HTML.
Directives are the one which instructs VueJS for doing certain tasks. Some of the built-in directives are v-if, v-else, v-bind, v-model, v-on, v-show.

What is Vue JS used for?

VueJS is an open-source front end JavaScript framework. VueJS can be used to build interactive UI’s and single page web applications. You can also construct small, interactive parts to be integrated with different technology.
Because of its templating syntax and component use, integrating and migrating existing projects to Vue is faster. VueJS can be great for startups and also for enterprise-scale applications.
Also, the learning curve for Vue.js is less steep than React, Angular. Vue is easier to learn than React, it also allows the use of JSX, for developers who want to adopt that style.
One good thing about the language is that it is optimized for developers. If you are developing a project with Vue, you can use the CLI(command-line interface) by the Vue team. It can simplify setting up a project.

Why use Vue.js?

Vue.js is a flexible and scalable technology that you can employ to build apps without using a lot of resources, which means it can be used for huge, modular SPA(Single Page Applications).
Vue helps you in avoiding time for writing boilerplate code by providing a lot of built-in solutions, which also saves your time in writing the code.
Most of the developers love Vue.js not just because it’s a great technology but also because it’s made keeping them in mind. There’s a graphical interface(Vue GUI), which can help you get started on your project without typing any cryptic commands.
Since Vue is newer, it’s developer had the choice of learning from the mistakes of other JavaScript frameworks such as Angular and React, especially the issues in Angular.
Vue apps are generally smaller in size and hence have a faster loading speed and also give high performance. Vue takes care of optimizations a lot on its own, so developers no need to worry about it.

Vue vs React

Both are front-end frameworks and popular as well, React has been in the front-end development field for many years and is dominating. Both Vue and React to use Virtual DOM.
While React was created by Facebook, Vue was created by Evan You, whose aim was to develop a framework that would integrate the best features from the already existing frameworks.
The main difference between Vue and React is that Vue uses templates with declarative rendering, while React uses JSX which is a JS extension.
When talking about the popularity, React is more popular than VueJS. 
Applications developed in Vue.js are comparatively smaller than the applications developed in React, which means the applications can load faster and give high performance when compared to the same application developed in React.

Vue vs Angular

Talking about performance, Vue is comparatively faster than Angular. 
Applications developed in Vue are smaller in size compared to applications developed in Angular.
When talking about the learning curve, Vue is easier to learn than Angular.
Angular is more popular than Vue.
Angular is used for developing large-scale enterprise-level applications while Vue is explicitly known and used to build small scale apps and is evolving in building enterprise-scale applications.

Vue.js in a nutshell

Vue.js is user and also developer-friendly, and has thousands of libraries and a great community.
The learning curve for Vue.js is steep as compared to other frameworks, which means you can easily get started with Vue. And it takes care of the optimization itself and is flexible and scalable.
Application build in Vue is smaller in size, which means it can give high performance.
