JavaScript is not a new piece of technology. But, it is being used to this day and it’s incorporated in various spheres of software, hardware, and various other forms of technological developments. The best part is that it’s still being expanded and upgraded. We will not see the end of JavaScript any day soon. One of the main proofs of this claim is of course the ReactJS.
We are talking about one of the most popular tech solutions tied to the world of JavaScript. What’s good about ReactJS is that it is an open-source library available to everyone interested.
Based on it, you can build different interfaces, mobile apps, web pages, and everything in between. If you’re eager to get straight to it you can immediately visit this website and get the wheels moving.
Also, if you’re still unsure how to approach this subject or if you should do it at all, you can read this article. Below we are going to cover some of the top ReactJS features that anyone with an interest in JavaScript should know. Let’s start.
Declarative Views
ReactJS operates very well in the domains of mobile applications and websites alike. It can be of great help when it’s necessary to build a new interface that will be modern, interactive, and above all else dynamic.
When building an app, viewing it in all stages is essential and this can be done through ReactJS. It is amazing when it comes to rendering views, components, and data updates.
Through the declarative view, you’ll do a favor to both yourself, your partners, and your code. By making it more readable and easier to debug, everyone’s job will be made much easier.
The Use of Virtual DOM
ReactJS has this amazing trait that whenever you have a virtual DOM in front of you, it can be rendered as a virtual version. Virtual Dom objects are a thing in ReactJS which is one of the best features you’ll encounter. The virtual version is a replica of the real deal.
We are talking about an exact virtual copy which is immediately created upon your request. While updating or tweaking your original DOM sometimes needs to be done, it is always a better option to do it virtually first before you do the real move. This way you can update and change it without the need to have anything on screen.
Handling of All Events
Every W3C object model cooperates extremely well with ReactJS. You could say that ReactJS has an event system of its own that is highly compatible with W3C objects. If you look at the native events that are located in the browser they’re seen through the Synthetic Event.
With ReactJS it doesn’t have to operate on its own but it’s provided with another interface or a parallel browser which is also tied to the original event. What this means is that you’ll never encounter fields or names that are not compatible with either software.
Another thing that needs to be factored in here is the fact that by using it you’ll rarely encounter memory overhead due to ReactJS’s pool of event objects and good event delegation.
JSX
You need to think of JSX as a way you can write code that appears to be HTML. It’s kind of like making a mixture of JavaScript and XML into one cohesive mass.
JSX makes building React components easier, as it recognizes them as the building blocks of a React user interface. It does this by making the code you use to make web page parts almost identical to the proper HTML you want to present.
This must be one of the coolest things about ReactJS, as people in the web developing domain prefer simpler solutions in most cases, and JSX offers precisely that.
Performance
React works adequately. It operates on principles of connecting data in one direction and following a pattern back. This pattern is called Flux.
It serves to manage how things flow in your app. With ReactJS, updates for what users see on their screens can be done, and with it, we can manage how the app behaves behind the display.
A funny thing React can do is use something called a virtual DOM (we mentioned it earlier) that aids in updating the screen more rapidly by putting new data next to the original design, comparing the two and only changing what’s necessary.
React Native
Imagine React Native as a special tool for ReactJS. The way React works on the internet with React DOM is the same way it works with react native. But it’s for making apps that work on devices like smartphones. It uses data, code, and interfaces that are made for mobile devices, not the web.
To start with React Native, you must understand some software basics of React, such as the above-mentioned JSX, components, and how things like information and features are moved in between the premises.
React Native also allows the use of special smartphone phone features while making your code ideal for both iPhones and Androids.
Component-Based
ReactJS operates by creating something out of small pieces called components. These items are like building blocks in construction. You put one next to the other and make what you will later see as a web page.
Every part of your application should look and feel like separate parts of these building blocks. Since they are written in JavaScript you can easily send important data through your application and keep the important stuff separate from what’s less important.
Components in React are used to design how it appears and how people will interact with it later on.
Conclusion
ReactJS is all about one thing. Having the use of the new tech that we have around. We talk of one that has not been around here before or used properly for that matter. It is an amazing tool to have as a part of your application. It’s what people want to see and want to use as fast as possible.
With React, you can add new items without re-making all that you already created. It is like providing your app with a fresh new look without the need to start from the ground up.
