TL;DR: There is no need to give up jQuery nowadays. It is great for developing various landing pages and similar sites. But when the project should use things that are more complicated than various sliders and smooth scrolls to anchors, like interacting with the interface, receiving and processing different data, it is better to use such a highly-efficient framework as React. If you’re building a simple website, then it makes sense to use jQuery. If you’re starting a more or less serious project, choose a more modern framework.
What are the undoubted advantages of jQuery?
Cross-browser compatibility. The jQ syntax is supported by all modern web browsers, and you can be sure that the stylish slider you create in jQuery and CSS will be seen by every site visitor, no matter what browser they use.
A convenient work with events and visual effects. Need to create a tooltip on mouseover? Start animation on click? Create the effect of falling snow right after page load? Request the user's data? All this can be easily implemented in jQuery.
Clear documentation. On the official resource, you can get acquainted not only with the library's capabilities, but also with all its functions, conveniently divided into categories. Read and implement.
The thousands of ready-made plugins are perhaps the main advantage. Don't want to create a photo gallery from scratch? There are tons of ready-made options on the net! Need a tooltip? Slide show? HTML form validation? jQuery does it all, you just need to find a plugin.
Let's be objective and try to highlight several disadvantages of the jQ library:
Performance. Experts claim that code in other frameworks (such as React) is faster than jQuery. But there is a problem – today it is almost impossible to verify this thesis, which is associated, firstly, with an increase in the speed of the library itself, and secondly, with an increase in the performance of computers through which users access the network. Moreover, the speed of the Internet is increasing every year.
Library size. jQuery weighs about 19 KB, which theoretically can affect the speed of loading a web page, especially on older computers and ones with an unstable network connection. However, here we return to the above-mentioned thing – most modern providers guarantee an acceptable Internet speed, so the overwhelming majority of users will not see any problems when loading a page with jQuery code.
The library allows you to manage the virtual DOM, component architecture, and their states. Many React apps rely on third-party libraries built and maintained by the programming community. The development of React applications requires a higher level of expertise, so it should be noted that mastering the library is more difficult and the threshold for entering this technology is quite high.
So what are the benefits of React?
Based on simple programming languages.
Extremely flexible application.
Using the DOM.
The possibility to withstand heavy loads.
Excellent cooperation with SEO. Search bots can browse the site more easily, so user interaction with your resource is improved.
An open data library.
Low weight of the database
Does React development have any downsides? Of course, there are shortcomings to any approach. And for React, they lie in the very architecture of the applications being developed. Simply put, applications are heavier.
Since React is an intermediate in the ecosystem of software frameworks, an application developed in React will be slightly larger than an application built using the native libraries from Apple or Google. That is, if you create, for example, an App for a loyalty program or for booking tables in a cafe, then it will take about 25-30 megabytes of the phone memory. However, in most cases, this has little or no effect on how users evaluate the app, given the capacity of flashcards and the speed of broadband Internet access.
The decrease in productivity is observed. Since any actions of a React application go through intermediate libraries, their speed is slightly reduced. However, if your mobile program doesn’t carry out any calculations, then no one will notice the increase in processor load up to 2% instead of 1%. Difficulties can arise when the size of the application is large enough, and we’re talking about a really complex software environment that takes hundreds of megabytes in the phone's memory.
The same goes for performance. The disadvantages of having an additional framework will only affect engineering or computational applications that code something, do some calculations or process large amounts of data right on a mobile device. In the other 95% of cases, React is the optimal way to run the prototype as quickly as possible and get started with the application.
ReactJS is a smart choice when building large applications and complex user interfaces. The library allows you to display large amounts of dynamic content that changes during user viewing. Its declarativity simplifies and speeds up the process of product development and release.
With this development tool, you can build a site, application, or specific function from flexible reusable components (tab bars, lists, etc.) without rewriting the code. Thus, it allows developers to create quality applications, with a flexible architecture that can be adapted to any further changes.
There is a trend among developers to opt for React. According to the State of JS, this library has the highest level of satisfaction and more than 70% of developers use it in their work. Since now most large projects are created using this JS library, we also use it in development.
