Without mobile and online applications, the world would not work in today’s world. From taxi bookings to meal orders to bank transactions, everything has gone digital. Because of well-designed frameworks that guarantee a pleasant user experience. One such powerful frontend library is React. This ‘what is React’ lecture will take you through the library’s basics and demonstrate how to utilize it with a simple demo.
Beyond only UI, React provides several extensions for full application architecture support, such as Flux and React Native.
Today, React’s popularity has surpassed all other front-end development frameworks. This is why:
The aforementioned arguments more than justify the React library’s success and adoption by a vast number of organizations and businesses. Let’s have a look at some of React’s features.
Note: “Is React JS frontend or backend?” readers regularly ask. Without a doubt, the front end is the answer. You may recall the “on-screen” portion of UIs by remembering that React is a front-end library that is exclusively used for “client-side” programming (building things that a user will see on screen in their browser window).
This isn’t simply for the sake of convenience; using JSX to update a DOM improves site performance and development efficiency significantly. How? It’s all about the Virtual DOM, the upcoming React feature.
If you don’t use React JS (and JSX), your website’s DOM (the process that allows objects to “change” on screen without requiring a user to actively refresh a page) will be updated using HTML. This is acceptable for simple, static websites, but it can be problematic for dynamic websites that require a lot of user involvement (since the entire DOM needs to reload every time the user clicks a feature calling for a page refresh).
React JS, on the other hand, creates a Virtual DOM when a developer uses JSX to control and update its DOM. The Virtual DOM is a duplicate of the site’s DOM, and React JS utilizes it to figure out which elements of the real DOM need to update when an event occurs (like a user clicking a button).
Consider a visitor who fills out a feedback form and hits the “Comment” button on a blog post. You’d have to update the entire DOM to reflect the change if you didn’t use React JS (using the time and processing power it takes to make this update). React, on the other hand, looks at the Virtual DOM to see what changed as a result of a user action (in this case, adding a remark) and only updates that part of the DOM.
This form of selective updating demands less computational power and loading time when it comes to a single blog comment, which may not seem like much, but when you consider all the dynamics and updating associated with even a fairly advanced website, it adds up rapidly.
If all of this makes sense, but you’re still stumped as to what React code is, keep reading. This React examples website will provide you with a visual representation of what React looks like. Each of the projects featured here provides an example of what can be done with React JS as well as a peek at the source code that was used to create it.
Meanwhile, if you’re still unsure about “what can be done with React JS,” keep reading. These easy projects curated by the official React website provide React JS templates to navigate through as you learn React JS.
Finally, if you’re searching for a React JS tutorial to go with those React JS examples for beginners, ReactJS.org’s Intro to React is a React JS tutorial that requires no prior experience or knowledge. This is an excellent place to start whether you’ve already worked with the React library or you’re still finding out how to install React.
Furthermore, React JS is an open-source project, which means that anyone can download and alter its source code for free. This also means that for any UI function you want to accomplish with React JS, there’s a React library for it. With React’s community-curated library add-ons, ranging from collections of specific UI features to whole React JS templates for constructing UIs from the ground up, your React library can grow tremendously.
We’d love to hear from you if you need advice on which JS framework or library is ideal for your project’s technical requirements, or if you need to establish or scale your React resource by hiring a React JS developer or a dedicated React JS development team.
Based on a well-practiced in-house process, we can reliably price quote even huge, enterprise-level applications within 24 hours if you already have clear technical specifications. Alternatively, based on your overall feature requirements, we can assist you with finalizing detailed technical specs for a React application. For further information or to get a quote Contact us!
