There is no doubt about how popular javascript is among developers these days. No matter if they are naive developers or they have done a lot of coding during their careers, most of them tend to use it to build their applications or projects. Angular and React are the top two developers’ choices in case of front end development tools from a few past years.

Difference between a library and framework

Some developers use these two terms interchangeably, but there is a subtle difference between these two. In definition, a library is a collection of reusable codes that developers mainly use it to solve common problems. There is a variety of libraries out there for solving different types of problems. For instance, we have libraries to solve mathematical equations and calculate the final answer. We have different types of machine learning libraries like Scikit, as well.

On the other hand, the framework not only gives us a lot of reusable codes like a library, but also it provides a structure or a skeleton for building an application. Therefore, when you decide to use a framework to build that application, you must design the whole architecture of the application based on the framework’s standards. Frameworks direct us to the way that we should design the structure, how we should start the application, and the number of components we ought to put them in interaction.

Generally, we do utilize frameworks and libraries to improve our speed and productivity. Due to the codes which are already tested and became ready to use, we can speed up the development process significantly.

Everything about React.js

ReactJS is an open-source library that is first introduced by facebook in 2013. The ultimate goal of this library is building interactive user interfaces. React stands on JavaScript and JSX bases and can offer different tools for developing reusable HTML elements. Many surveys show a lot of developers like ReactJS more than any other libraries. This will become obvious when we take a look at the StackOverflow developer survey in 2019. This list presents a list of the most beloved web frameworks.

React is the most popular web framework

There are also so many big applications and websites that are build based on react. For example, Whatsapp, Instagram, PayPal, and Uber are using React library. The reason behind the popularity of React is its high dynamic. It also offers you a huge amount of freedom to choose which other libraries you would rather be using. React also has a huge community which means all the problems you might face, have been solved by other guys out there. So, you will be able to use many third-party libraries, packages, tools, and extensions without any difficulty.

Everything about Angular

At first, Google introduced Angular in 2010. Firstly known as Angular.js, it took the community massively by storm. Afterward, the team released angular 2 which was absolutely in different shape and form in comparison with its predecessor. To help people to remember this framework easier, they have decided to drop that .js and call their new product Angular. The negative point about this new framework was lack of backward compatibility. In other words, developers who had used the previous version had to rewrite their applications. We should point that out this was not the end of the story. Because of sets of breaking changes, this bad experience has repeated to developers over and over.

React and Angular comparison

As we mentioned above, the final objection of this article is all about helping you to select a better choice when it comes to starting to build your new application. Below you can see some factors that we have considered to compare React and Angular.

React VS angular

 Learning curve

The framework or library you choose must be rocket science. Because otherwise, your team will have major problems with getting up-to-speed quickly. Angular is very famous for having a very steep learning curve. Angular is widely known as a fully developed and complete solution. However, this means that developers will have a difficult time learning and mastering this framework. There are so many concepts you need to learn such as directive, modules, pipes, etc.

On the other hand, react is just a library and not as complicated as Angular. Therefore, the number of concepts you need to understand is lower. For working with the react, first, you need to learn JSX (a method of writing HTML with javascript code) syntaxes. When you are done with basics, you can develop your knowledge and learn concepts like react-routing and redux.

Talent availability

One of the biggest concerns of managers is to find and assign an effective member to their team. Because react is a very popular front end library, the chance of hiring a developer who knows how to work with react is much higher than angular. Therefore, managers would be able to negotiate about the project and payment method with job volunteers and hire the best person who suits them the most.


The stability of the framework and the library is a very crucial subject for the business. If the framework is not stable, in the short future it will make the work harder for the development department. Consequently, it brings more costs to the company and triggers customer dissatisfaction.

The angular team uses to publish an update every 6 months. it means you need to keep trying to apply so many changes before the depreciation of the old API. In contrast, you do not need to worry about this issue. As mentioned previously, lots of big companies (like twitter) are using react. So, Facebook is not keen to present big changes that could impact these big names.

Development time

React is very easy to set up and use. In addition, you can start building your application at a very fast speed and add features to it. On the other hand, Angular is much more complicated and there are lots of unnecessary syntaxes to execute a simple task.
