This is a guest post from Udemy about their React courses, who say:

“We’ve been working super hard over the last 6 months to sharpen up our content, and now have over 12 million people using just the React courses alone.”

Practical use of React in 2020

 The majority of people who start their front-end path ask themselves whether it’s worth learning React in 2020. The short answer is yes, the longer explanation of why follows.

While there are gossips in the development society that React is becoming outdated, according to last year’s research, more than 30% of respondents are using React and more than 2 million people are learning React on Udemy. These facts make it the second popular web framework after jQuery and the third one among the responses of professional developers giving the first place to the same jQuery and Angular. However, Angular is a fully-fledged JS framework, while React is a JS library, so it’s not correct from the technical point of view to compare React with Vue, Angular, or other frameworks. However, knowing React will definitely help you, if you decide to pursue a development career.

Let’s dive straight into 5 most widespread cases when it’s applicable:

Working with dynamic interfaces

If you plan to build an application with a dynamic user interface, React will be a perfect choice. As React uses JSX and Javascript, building dynamic components becomes/is easier.

Stability during the code management

If you search for solid code-base management, you would enjoy React. Taking into account the uni-directional nature of reacting, the child components do not depend on the parent ones, so that changing the former will not influence the latter giving your code more stability.

The need to use similar elements

If you have several type forms or other elements that will be used more than once, you will be able to reuse them. React allows you to reuse previously built components saving your precious time.

Performance boost

If you are aimed at improving the performance of your application, choose to React. It uses VDOM (shortened from Virtual Document Object Model). The main issue of Traditional DOM that it was never intended to be used with Dynamic interface. VDOM in its turn builds a lightweight tree from JavaScript objects to simulate a DOM tree. Then it translates this tree into HTML, which is inserted or added to the desired DOM element, which causes the page to be re-rendered in a browser optimizing the performance.

Improved Security

If you care about security, look at React’s side. It does not mean that you don’t have to use any other security protections as the threats occur on different layers of your application, but with React you can enjoy the benefit of having an inbuilt Cross-Site scripting attacks prevention.

Last but not least, React is considered to be the easiest one to learn because of being lightweight and intuitive. But it’s up to you to dive deeper into it.

There are many more reasons to opt for React, so don’t hesitate to learn it, since it’s really unlikely that it will lose its primary positions in the list of the most popular web frameworks on the market anytime soon.
