Vue vs. other frameworks
In comparation with other frameworks, Vue.js is faster, it scores higher in benchmarks than Angular or React (since it is more core library focused and has better optimization), it provides more reactivity, allows more reuse of code, has a low learning curve, and is faster to code in.
What does Vue offer?
- Reactive interfaces
- Declarative rendering
- Data Binding
- Template logic
- Event Handling
- CSS transitions & Animations
- Custom filters
- Computed properties
- Components & Nesting – helps you with organizing your applications
Why should you learn Vue?
Well, I could tell you many reasons, but it all depends on you. Firstly, you should always keep in mind what are you trying to obtain by learning Vue. If you want to get a job, things might get complicated because nowadays employers tend to overlook. Maybe it will take a while until recruiters will appreciate Vue Js. On the other hand, if you are a startup specialized in developing custom web application, then Vue technology is amazing. Its structure is accustomed, it will be easy for you to get acquainted with it, and the most important, it takes 15 minutes to pick it up. Furthermore, unless it is a combination between Angular and React, Vue does not require much experience and it is efortless to be comprehended, just because all of its documentation is accessible to everyone.
Vue and Reactivity
Vue uses the getter/setter strategy to convert all the objects in its data option, the converted objects setters in turn notify a watcher if the object changed its properties which causes a re-rendering of the Virtual DOM.

A really important part in the lighting speed rendering of components in Vue is the Virtual DOM technology. The real Document Object Model (or DOM) is a structure that’s present in all modern browsers. It keeps all your HTML in a tree of objects (that’s where the Object Model comes from), this structure allows the developers to delete/add HTML to the page, add events, change CSS using the DOM API.

While it may be a great feature by itself it has a big downside, it’s quite slow for modern websites. Imagine trying to find a node in a tree with a couple hundred or even more levels just to change a line of text, then going back and adding another character.
While other frameworks use similar technologies, mainstream virtual DOM implementations suffer from performance issues like re-rendering, requiring optimizations, Vue 2.0 tackles this problem by combining virtual DOM with its reactive dependency tracking system, so that the system can automatically and efficiently determine when and what to re-render, freeing the developer from unnecessary optimization work.
As a conclusion, we can all agree upon the fact that Vue is the best option. Even studies show that comparing the most 3 popular frameworks: React, Angular and Vue, the last one is the most favored with 10.88M visitors and its raising each month by 9.5%. Contrast to Angular: 3.44M (-28.55%) and React 5.69M (-12.92%). In the next five to ten years, Vue will become more and more in vogue. Nowadays, there are many websites (Alibaba, Xiaomi, Baidu) that use Vuejs as a central frontend technology.
