JavaScript is a lightweight programming language, a popular choice for application development. In fact, the JavaScript framework popularity is so massive that there are dozens of libraries providing solutions for any code-related problem imaginable. Whether you’re developing a web app or a cross platform app, JavaScript has a framework suitable for your needs. 

The three biggest jewels in JS crown are Angular, React and Vue frameworks. Which one is more popular?  They all solve specific problems in their own way. In this article we will discuss their differences, advantages and disadvantages to help you pick the best framework for your goals.

What is Angular framework?

Angular is a free, open-source JavaScript framework based on TypeScript (a programming language that’s built on JS) that is used for mobile app and web development. Angular is designed to support easily scalable applications. Angular can manage DOM (document object model, a programming interface for HTML and XML), give a high abstraction level and put components into rather strict, but well-composed structures.

As a platform, it consists of:

  • Component-based frameworks;
  • Essential developer tools;
  • Massive, well-integrated libraries covering various features, from routing to client-server communication.

Additionally, Angular has a following of more than 1.5 million active developers and content creators in case external help is required.

But how does it work? Every application consists of components: building blocks that constitute the foundation of an app. Angular components include а TypeScript class that defines behavior, an HTML template and a CSS style sheet. This is how Angular components work:

  • You define a component’s application logic—what it does to support the view—inside a class. The class interacts with the view through an API of properties and methods. The usage of components in a template is defined by CSS selectors (attributes that determine what elements will answer to a certain set of CSS rules). The corresponding HTML elements will become instances of components.
  • Angular is instructed on how to process and render the components by the HTML template.
  • The appearance of HTML elements in a template is defined by an optional set of CSS styles.

Advantages of Angular

 

One of the main reasons for Angular’s popularity is secure data binding to HTML elements, but this framework has more benefits to offer:

  • Angular suits large, scalable projects. You can go from a single-developer scale to a development team scale anytime with minimal efforts.
  • Typescript foundation serves for a strict, consistent and clear code, making it easier to test, debug and support a large codebase.
  • Basic app functionality and UI (user interface) can be developed with Angular alone, with no other libraries required.
  • The modular nature of Angular allows developers to divide code into reusable chunks.
  • The support of the Angular development team, Google and a large community of creators.

Angular framework benefits

Disadvantages of Angular

Despite possessing a fair share of benefits, the Angular framework has some flaws:

  • Shows relatively lower performance, but it’s improving with every new update;
  • Limited SEO options;
  • Angular is more complex and strict than Vue or React, which makes it harder to learn.

What is React framework?

React is a free open-source front-end library that is used to create user interfaces and components for said interfaces. It can also serve as a base for mobile or single-page applications. React is described as declarative, efficient and flexible by its development team. Its way of handling web page rendering is dynamic and responsive to user input. 

Like in Angular, React interfaces are built using components. The components define what’s going to appear on screen via HTML, CSS and JS. React adopts JSX and Redux to enhance development possibilities. There are multiple templates and instructions for React online. 

Advantages of React 

The biggest advantage of React is its performance and speed, achieved by implementing a virtual DOM and various rendering optimization models. This benefit serves to provide a more flexible and dynamic UI.

Real vs Virtual DOM

Here are some other React benefits:

  • The framework is relatively new and modern, so developers are interested in it;
  • React is relatively easy to learn: the documentation is highly descriptive, the design of the framework is simple;
  • The server-side rendering support is nearly flawless and well-suited to content-based applications;
  • An adequate toolbox is provided to help development teams;
  • Functional programming concepts implemented in React ensure comprehensive and easy to test code;
  • TypeScript and Microsoft flow can both be used to create React-based applications;
  • Easier migration between versions;
  • Skill earned working with React can be transferred to work with React Native.

Disadvantages of React 

Despite many considerable benefits, React has some flaws a developer should keep in mind when choosing the right framework:

  • React may be too flexible as it is more of a library than a framework – there are dozens of solutions for each problem, so developers have to decide on the correct path on their own;
  • Some of React’s features, like the absence of class-based components or mixing templates with logic, may be a serious obstacle for developers that are used to Object-Oriented Programming;
  • Pace of development may slow down because of many updates and new feature introductions as React is an ever-evolving and fluctuating framework.

What is the Vue framework?

Vue is a progressive, open-sourсe, front-end framework used in UI and single-page application development. The development team describes this framework as approachable for anyone who knows JS, HTML and CSS, as well as versatile and performant. 

Vue is based on the model-view-controller (MVC), a traditional architecture. Its view library is focused on the view layer, making it easier to integrate this framework into other libraries and into projects already in development.

Model View Controller Architecture

Advantages of Vue

The biggest advantage of Vue is it’s small size. For a mere 20KB of space, developers get to experience higher performance, more flexibility and speed. Of course, there are other benefits to the Vue framework:

  • Vue has many integration possibilities: parts of existing code can be put into projects with ease;
  • Optimized HTML. While similar to Angular, Vue can maintain HTML blocks better using its own components;
  • Usage of virtual DOM boosts the user experience;
  • Two-way data binding makes updates and changes in architecture easier to implement, including real-time updates;
  • A lot of reusable templates can be created using Vue, improving scalability and reducing development time;
  • A decent toolbox is included in the base library.

Disadvantages of Vue

Now that we’ve discussed the pros of Vue, let’s explore the cons to keep in mind when choosing this framework for development:

  • Lack of resources. Vue is a relatively young framework, which means that while it can handle smaller projects just fine, tools for more complex applications are still in development. Plugins from other frameworks can fix this, but large project support is not possible with Vue alone;
  • Due to Vue being relatively new, there is a lack of skilled developers.

Angular vs React vs Vue

Which is better, Angular, React or Vue? There is no definite answer for this question. To help you choose one framework over another, we prepared a table for comparison.
