What Is Progressive JavaScript Framework?

Vue.JS is known as a progressive JavaScript framework. Evan You, an ex-Google employee, developed it. Vue.JS is used for building user interfaces and is focused on Single Page Applications (SPA). Many also use it to create beautiful web interfaces. Vue.JS is a progressive framework that’s becoming increasingly popular.

But what makes Vue.JS progressive? How is it different than any other framework on the market? Most importantly, why is an increasing number of developers moving on from React.js and Angular to Vue.JS? What is the progressive JS framework?

Progressive JS Framework

In short, Vue.JS isn’t just a progressive framework; it is the progressive framework. At this point, Vue.JS and progressive JS framework are pretty much synonymous.

Okay, so Vue.JS is pretty much the only progressive JS framework out there. But what does make it progressive?

First of all, Vue.JS is lightweight, fresh, and fairly simple and straightforward. Despite being flexible and simple, it is also very powerful and offers a variety of features. Vue also allows you to provide any app structure that you want. That’s not something that Angular would allow you.

So, it is easy to use, very powerful, and extremely versatile. That’s fairly progressive, wouldn’t you say? The mentioned qualities and many others earned Vue the “progressive” badge. Oh, and it is open-source, which means a lot in the dev world.


If you want to create a single-page application, there is no question about it – you should go with Vue.JS. If you’re wondering how it has earned its namesake, here it is. Vue essentially acts as the View, which means that it lets you display data portions. That’s unique and pretty much amazing.

Ease of Use

If you haven’t used an app framework, you won’t struggle with Vue, as you would struggle with any other framework. That means that Vue is great for beginners, if not even the best choice.

If you have experience with other frameworks, don’t worry. Vue’s core library is pretty much about the view layer. Therefore, you can pick it up, integrate it with third-party libraries, and use it with existing projects. So yes, you’ll get used to Vue quickly.

If you are an HTML developer, you’ll find that Vue’s learning curve is rather forgiving.


In itself, Vue.JS uses fairly basic docs and is lightweight. Vue works as an interface layer, meaning that you can put it to use as a light feature in pages. That is much better than a full-blown SPA.

Virtual DOM

Owing to the implementation of its virtual DOM, Vue tends to perform better than other frameworks. As a result, computation is inexpensive and allows you direct access to updates. If you want to make changes in DOM, you can do it just once by using the appropriate function.

Two-Way Binding

Vue has the two-way binding on texture elements and form inputs thanks to its v-model directive. The v-model directive is used for updating data regarding user input events. Vue can base its element update decision on the input type.

HTML-Based Syntax

The HTML-based template syntax that Vue uses allows the user to bind Vue’s instance data to the rendered DOM. That, in turn, allows the user to save reusable pieces of code by extending the most basic HTML elements.

The Downsides of Progressive JS Framework

Of course, Vue.JS does come with its own set of downsides. Although the developers are doing their best to make the most out of the open-source aspect of Vue, it still isn’t a standard.

For one, the developer can’t get access to application state operations. With smaller projects, this isn’t too much of a disadvantage. However, when it comes to large-scale projects, this can complicate the debugging procedure, and slow down the entire development process.

Now, although Vue.JS is “progressive,” it still doesn’t render as fast as React.js, which isn’t an ideal state of things. Templating also isn’t all that flexible, and neither is the component approach.


Although Angular isn’t a progressive JS framework, it is as close as it gets without being Vue.JS. Angular is a full-featured dynamic framework that works perfectly with dynamic single page web apps. Although it is older than Vue and lacks in many respects, it remains the favorite of many.

What makes Angular so great is the fact that it wasn’t built to be a JS framework. It started as a tool that allowed the front-end, back-end, and designers to interact. However, many use it as a JS framework now.

Cross-Browser Compliant

Angular automatically handles the codes required by each browser out there. That means that you only need to write the code for a single browser.

User Perspective

Angular allows the developers to do test runner and end-to-end setup, meaning you can test the web app that you’re working on from the user perspective.


Model-View-ViewModel or MVVM, for short, is a pattern, which is essentially a take on the traditional MVC software design pattern. It isn’t a disadvantage or an advantage.

Vue.JS vs Angular

Although Angular isn’t exactly a progressive framework, it is currently the closest thing to Vue.JS. From the learning curve side of things, Vue.JS is much better. Getting used to Angular takes time.

Angular is very “opinionated.” That means that it dictates the way you’re supposed to structure the apps that you’re making. On the other hand, Vue is based on installing the plugins that you want to use. By itself, it’s more of a library than a framework. It becomes a customized framework as you build it, which works perfectly with its open-source characteristics.

When it comes to performance, Vue is slightly ahead of Angular. Vue has a simpler programming model to thank for this.

Should You Go Progressive?

The answer to this question is probably “yes,” but not in the way you think. In truth, you should know how to use both Angular and Vue to reach your full capacity as a developer.

On the one hand, Angular is great for getting deep framework knowledge and is used for creating complex applications. After learning Angular, Vue is going to be a breeze. On the other hand, Vue.JS is a progressive app that’s likely to stay. It is probably the future of JS frameworks.
