Angular vs. React: A complete comparison guide .

The choices for front-end development libraries and frameworks have become highly competitive. Of all the JavaScript frameworks and libraries, Angular and React are the most popular among developers. There have been tons of discussions on the topic of Angular vs. React. Therefore, we thought it would be appropriate to highlight the in-depth differences between Angular and React, helping you choose the best one for your next or existing project.
How it all started - a brief history
Angular is an open-source JavaScript framework written in TypeScript. It was developed and launched by Google and is compatible with several code editors. To build dynamic web applications and websites, you need to use Angular in your front-end development.

The first version was called the "AngularJS," the second version and a complete rewrite of AngularJS. Angular use in one of Google's most important projects, Google AdWords.

React is an open-source JavaScript library developed by Facebook. It base on JSX (PHP extension) and JavaScript. The React library breaks down a web page into individual components and simplifies user interface development. React was developed in 2012 when Facebook's ad management became complicated with simple HTML coding. It opened in 2013 and has since by millions of developers. React has been widely used in the Facebook and Instagram user interfaces.

| Popularity

Angular has been popular until 2016, while React continues to gain popularity by leaps and bounds. Stack Overflow showed that both Angular and React were equally popular among developers in 2018. Since then, React has gained more users than Angular and become the most popular open-source JavaScript library. In 2020, React will be ranked 1st on most desired frameworks, and Angular will be ranked 3rd. According to a Stack Overflow survey, more developers said they choose to React over Angular, so React is so popular.

| Google Trends

Google Trends doesn't show usage, but it does establish which framework. It shows which frameworks people are curious about React is the most talked-about framework, while Angular's popularity has dropped significantly.

| Maturity of frameworks

The maturity of frameworks is a crucial point to consider before adopting one. Yes, you would want to use cutting-edge technology. However, it is always essential to maintain a balance between new technology and time-tested approaches.

Choosing an immature tool has its challenges. The agency may not be well designed and may be flawed. Also, the community base may not be significant. So if you run into a problem, it will leave you to solve it alone. The response can judge these frameworks' maturity from the GitHub community, indicating that both React and Angular are pretty mature and a large community base for both frameworks. Over time, skilled developers have adopted both frameworks and any issues with community support.

The Angular framework on three layers: Models, Views, and Controls. It has a complex and fixed structure. In Angular, developers divide code into separate files, making it easier to reuse templates and other projects' regulations.

The React library does not have a fixed format in which to write code. Code written with the React library is well structured and readable. The use of component trees allows the code to be structured logically. The library also has functional programming, which makes the declaration of components declarative.

| Development speed and productivity

The CLI of the Angular framework provides an excellent development experience. It creates a brilliant workspace and allows you to design components with just a few lines of code quickly. Several built-in processes can easily solve problems.

The use of third-party libraries has an impact on the speed and productivity of React development. There are many tools in React. The use of devices varies from project to project, which means that more time needs to invest when applying to a new developer for an update.

| Backward compatibility

Angular four is backward compatible with Angular 2 and beyond. However, versions smaller than Angular 2 are not back-compatible, which is one of the drawbacks of Angular as a JS framework. React is a different story. React 16 is fully compatible with previous versions and even supports asynchronous rendering. It is fully open-source and under MIT license for GraphQL and Jest. Angular two is not compatible with AngularJS.

| Performance

The most important criterion when discussing the differences between Angular and React is performance. Both frameworks use the Document Object Model (DOM) to evaluate performance. The DOM is a programming interface that organizes HTML, XHTML, and XML documents into a tree. The tree allows scripts to interact dynamically.

In an actual DOM, the entire tree behind the framework update when a change occurs, which slows down the process and reduces the framework's performance. This problem solves by a virtual DOM, which tracks changes and ensures that only certain elements update without affecting other parts of the tree.

Angular uses a real DOM in its applications. For pages that are updated from time to time, a real DOM is ideal. Also, the size of the library is vast, which makes applications using Angular slower. UpWork, for example, uses one of the most popular Angular apps because it requires few frequent updates to the user feed.

React uses a virtual DOM and is best suited for websites that need regular content updates. The size of the library is also tiny, making it lighter and more dynamic. Instagram, for example, uses React because of the need for frequent user feed updates.

| A simple update

In this section, we will look at the update process in Angular and React. Before choosing a framework, you need to make sure that it can add new elements to your project. Selecting the proper framework is essential for the success of your JavaScript project. To transition from an older version to the latest version as smoothly as possible, you compare the migration process and time.

Angular releases a significant update every six months, with a six month amortization period for each version
The update process is straightforward, and the whole framework ships in separate packages.

Scripts that use React can easily switch from the old API to the new one, and as you can see from the Facebook interface, the API is very stable. As you can see from Facebook's interface, the API is very durable, and updates are smooth, and unlike Angular, migration is straightforward. The main versions are stable and independent but provide a fast-moving library.

| Data Binding

The Angular framework uses a two-way binding approach, where changes to UI elements automatically change the state of the model and vice versa. The React library uses a one-way system, which means that UI elements can only change after the model's state. While the two-way approach may seem more straightforward, React's one-way system is more effective for projects with large amounts of coding.
Flexibility and performance
There is a big difference in the flexibility offered by Angular and React.

React offers developers a wide range of tools, libraries, and different architectures. An experienced React team can pick the tools they need first and deliver a highly customized app.

Angular does not offer the same flexibility as React: Angular components can only be used within other frameworks and must embed the HTML application code. This rigidity is not helpful for apps that need to in near real-time. One of the most exciting aspects of Angular is that each component has a lifecycle, called the Angular Lifecycle.

| A developer's perspective

It's easy to get started with Angular, but it can take a while to get your project up and running. React takes more time to set up than Angular, but you can create a project and build an app relatively quickly. React takes more time to set up than Angular, but you can create a project and build an app relatively quickly. Also, unlike Angular, React allows you to add new features using a variety of libraries. Also, unlike Angular, React does not have Model and Controller components.

As we've already seen, React is more popular with developers on GitHub and NPM; React has over 135k stars on GitHub, which speaks to the popularity of this framework in the developer community. However, according to Stack OverFlow's 2020 surveys, Angular is more popular. In a separate study, nearly 75% of React users said they would use it again.

React has a large community because of its Virtual DOM implementation; with Virtual DOM, apps can update and render faster than Angular apps. However, Angular is supported and widely used by Google Adwords, which means that the community on all platforms supports both frameworks. Community support can help you resolve any issues that arise.

Angular vs. React: when and what to choose?
