Advantages and Disadvantages of React

I lately had a job interview the place I used to be requested questions on React and JWT. I managed to reply them and bought the job. Nevertheless, I could not shake the sensation that my preliminary causes for utilizing React, reminiscent of ita recognition and being taught by my faculty teacher, have been considerably missing. Now that I’ve gained extra expertise with varied programming languages and have a broader perspective, I really feel it is time for me to confidently articulate the benefits and downsides of React.

I nonetheless cannot definitively say whether or not React is nice or unhealthy, so I will record some execs and cons which are generally mentioned amongst builders.


  • Digital DOM
  • Reusable Parts
  • Scalability
  • One-Approach Information Circulate
  • React Native (for cellular app growth)
  • Web optimization-Pleasant
  • Robust Neighborhood Assist
  • Straightforward to Be taught
  • (Reputation)


  • Improvement tempo
  • Lack of documentation
  • Not MVC
  • JSX

Digital DOM
React makes use of a digital copy of the DOM, permitting for quick updates. In a Single Web page Utility (SPA) like React, modifications made on the web page can pause the loading of a web page. React’s Digital DOM idea acts like a replica of your actual DOM, sustaining cached reminiscence and avoiding the necessity for re-rendering the DOM bushes repeatedly. This ends in higher app efficiency.

Reusable Parts
React is made up of a number of elements, every with its logic and management. There is no have to create elements from scratch each time, making it straightforward to take care of and dashing up the complete growth course of.

React’s modular design makes it simpler to scale in comparison with many different platforms. Every UI will be damaged down into smaller items, permitting you to easily add elements or change previous ones with extra sturdy variations.

One-way Information Circulate
React’s one-way information circulate, or unidirectional information circulate, ensures a clear information circulate structure. Information from a mother or father, referred to as props, can solely be handed right down to its youngster elements, not vice versa.

React Native
React has been upgraded to develop native cellular functions for each iOS and Android. Instagram, Fb, and Netflix cellular apps are developed utilizing React Native.

Web optimization-friendly
React is appropriate for creating Web optimization-friendly internet apps because of server-side rendering, dynamic rendering, and meta tags. For instance, React can scale back loading time and improve rendering pace.

React is an open-source framework with a big group of builders, making it straightforward to seek out assist and help.

Straightforward to Be taught
(This appears reliable, however) React is alleged to be straightforward to study as a result of it requires fundamental information of HTML and CSS.

That is simply my opinion, however discussing its recognition is essential along with its benefits. In 2022, JavaScript was probably the most broadly used programming language with over 60% market share. The most well-liked JavaScript frameworks have been Node.js within the first place and React within the second, much more fashionable than Angular. Due to its recognition, the group is giant, and extra tutorials can be found.

Improvement tempo
React has constantly developed, requiring builders to relearn. Some discover this uncomfortable.
Lack of documentation
Because of steady growth, acquiring correct documentation will be difficult.

React covers solely UI or View, requiring different instruments for Controller and Mannequin, reminiscent of API and routing.

This syntax extension generally is a barrier for brand spanking new builders to study React because of its complexity.

These are the benefits and downsides typically mentioned amongst builders. For now, as a junior developer, I ought to hold these in thoughts and be on the identical web page with different builders to know the React approach. Ultimately, I can type my opinion based mostly on the factors mentioned above.
