In this article will be comparing the three cutting-edge UI development technologies that React js, Angular and Vue JS. We learn about the key differences that make them so distinct.
All of these technology stacks have been replacing pure server-side technologies, and we’ve slowly progressed from server-side applications to more distributed applications where a part of the job is done on the client-side and apart on the server-side.
So let’s compare the three technologies and learn about the factors that make them stand out.We learn about the features, use cases and where they are applied, the performance, how they handle the data, the languages they use, and the testing mechanisms.We learn about the dedicated user community that backs these technologies and finally will see the growth curve.
- Use Cases
Features & Languages
Now the entire page is broken down into several components. and each component performs a specific task. for example, one component handles the login and the other one would display icons and images and so on. All these components are then put together to form a single-page application.
Moving on react was developed and maintained by Facebook, but Angular was built by Google, and Vue was developed by Evan You.
React represents the view part of the MVC framework, and Angular is a full-fledged MVC framework in itself. And Vue, on the other hand, is focused on the view and the model layer of the MVC framework.
Now, what exactly is the MVC framework?
MVC framework is an object-oriented design principle that mandates the separation of control, meaning one thing can only do one thing. So the model deals with the entity classes, the data, and the business logic, while the view deals with the representation and the UI logic of the application and the controller drives the functionality of the two.
Any changes can be easily factored in, isolated, and as a result, testing becomes a lot easier.
Moving on now, let’s look at the use cases from the business perspective. In terms of react,We have top websites like Facebook, Instagram, Netflix that use react. On the other hand, we have Angular that is used by Nike, HBO, Forbes’, Sony and vue is commonly used by Alibaba.Com,Grammarly.com, Adobe.
Now performance is a very crucial feature, Now the moment you build an Html view and render it into the browser. This view to the user is basically just Html.
if you look at the internal working, the code is actually converted into a balanced tree structure. This B -Tree algorithm is extremely fast. So if the user makes any changes to the UI, the changes are reflected immediately. This is facilitated by the B-tree algorithm.So as a result, the performance is improved.
So how does react make use of this tool? It uses a virtual Dom, Dom is an API developed by W3C. It stands for Document Object Model and defines how the document is accessed and manipulated. This Dom parser converts HTML CODE into an inverse balanced Tree structure. So React uses the virtual dom, but Angular uses the real dom and Vue uses the virtual dom again.
Now the virtual Dom looks the differences between the current and the previous HTML pages and only changes the parts that need to be updated.
Angular, on the other hand, updates the entire tree structure regardless of any changes made or not, and Vue again only updates the ones that have changed .
Since there is no time spent on making unnecessary changes to the entire tree react as extremely fast. On the other hand, the real dom updation is time-consuming, risky, and error-prone. Vue also ensures faster and bug-free performance.
Now let’s talk about data binding, the core reason why we would use single applications.
Now consider a scenario where you would log into an e-commerce website as a user 1, then you should be able to see the items in your shopping cart while user 2 would be seeing different items in their shopping cart and so on, so identifying the user and retrieving data corresponding to that specific user is facilitated using the help of data binding.
Data binding is a process that allows an Internet user to manipulate the page elements using a Web browser. now it is used in interactive components such as calculators, tutorials, games, etc.
React supports one-way data binding, meaning you can take the data from the view and push it to the model, or vice versa. And on the other hand, Angular uses a two-way data binding while Vue, also uses a similar data binding.
In react every time the model state updates, the view changes accordingly. However, the reverse is not true. In the case of ANGULAR, any changes made to the view are immediately reflected in the model part of the architecture, Vue follows the same principle.
Now, this hugely influences the performance due to one way binding react is modular and fast-improving the performance. Angular two-way binding adversely affects the performance and Vue, on the other hand, performs according to the input type.
Angular also does something better. You can also write code for an angular application using a new language developed by Microsoft called TypeScript. It is a compiled language and is very similar to Java and C# in terms of syntax.
Let’s move on to testing now Jest is a framework or an API that is developed by Facebook and is used to run tests on React applications to ensure that they are bug-free. Now it is embedded in every React Project requires zero configuration.
Angular, on the other hand, uses the Jasmine framework. this framework allows various functionalities to write different kinds of test cases. This also ensures that the application is Error-free.
The Vue CLI or the command line interpreter has built-in options for unit testing with the help of jest or mocha. Now Vue typically has single-file components and hence these components can be tested in isolation. This makes it modular and extremely fast.
Now let’s talk about community support. Since all these tools are open-source, they have a large developer community. There are a few popular GitHub repositories for React, such as reactjs101, the Reactjs.Org, and so on. You can raise queries, solve and connect with the larger community that’s working on react. Vue also has a few popular repositories. You can comment, download third-party plugins and also explore these stacks even deeper.
All of them surely have a very happening community. At the time of writing, there were about more then one million repositories, five million commits, and one million issues with respect to React. Here are the figures for Angular and here are the figures for Vue.
According to NPM Stats, over the past two years that have been approximately 360M reacts js, downloads that have been around 38 million downloads for Angular and around 63 million downloads for Vue. Now let’s look at the future scope.
Learning a new technology always comes with questions like what’s in it for me? What’s its growth potential? How far will it take me in my career and so on.
So let’s go ahead and see the growth rate of React, Angular end Vue. According to Google Trends, over the past 12 months, the React has been on a way faster upward trajectory than Angular and Vue. Now, this indicates that React is growing faster than the other two with respect to popularity, industry, adoption, and community support.
So with that, we conclude this article. So I hope this article really helped you gain clarity about these technologies. Thank you so much for reading.
