At SF AppWorks, we aim to help your business stay modern by developing software and apps for you. In this article, we’ll be discussing all things React JS, including what it is, how it works, essential features, and other answers to your burning questions.
What is React JS?

Why Use React JS?
Here’s what we know so far:
React JS is used to build user interfaces with reusable UI components since it acts as an open-source library, and it’s used to handle the view layer for the web on mobile applications. In addition, because you can reuse code, developers don’t have to write everything out in raw form, which saves time and minimizes errors.
In addition to all of this, React JS has two key features that developers find incredibly helpful:
JSX is used to update and modify the DOM more efficiently, especially since it’s compatible with all web browsers.
For the more interactive websites that aren’t using JSX or React, the DOM modifications will result in a much slower reload time. Of course, if the developer is using JSX to modify and update its DOM, then React JS will automatically create a Virtual DOM.
The Virtual DOM is basically a carbon copy of the site’s DOM. React JS uses this copy to scan and analyze which parts of the primary DOM need to be changed when an interaction happens (i.e., when a user clicks a button).
This allows for selective updates and modifications rather than whole updates that would reflect any changes that happen. This takes up less loading and less computational power, which becomes extremely valuable when a website is filled to the brim with content and relies on heavy user interaction.
Is React JS a Framework or a Library?
Is React JS a framework? Or, is it a library?
If you’ll recall, we mentioned that React JS acts as both a library and a framework. Primarily, React JS is an open-source library for building interactive user interfaces. This library, in particular, allows for reusable UIs to cut down on time and to minimize errors.
While React JS also functions as a framework, it cannot be defined as a framework alone. Basically, if you were to search for the answer on the internet, you would find that most people refer to React JS as a “library with additional framework functionality”. What a framework does, essentially, is it allows for the inversion of control. In other words, it’s there to solve architectural and structural problems on a coding level.
But in React JS, the framework functionality doesn’t actually solve any architectural or structural problems. Instead, it serves the purpose of providing the developer with a set of methods to handle said problems. In fact, React JS does not work within any template design pattern nor does it push the structure of applications in any direction.
Its framework functionality hangs in the balance of being able to handle view with the input framework—which React JS handles pretty well.
React JS Examples
To give you a clearer picture of what React JS is exactly, we’ve compiled a list of React JS projects for you to take a look at. These projects were all created by the React JS community:
- The implementation of the iOS calculator
- The Simple React app for searching for Emojis
- The list of Pokémon via live search
- The Simple product comparison page
- The Simple Bitcoin price index using data from CoinDesk API
Should You Familiarize Yourself with React JS?
The answer here is simple—yes. React JS is arguably one of the best tools out there to help you successfully and efficiently build user interfaces with minimal issues. Understanding React JS will help you better communicate with your app, software, and web developers to take your business to the next level.
