React JS is a library that contains a range of components designed for web applications. These components can be anything from grids to buttons, labels to texts. This distinction is important, as it is part of what helps to make React JS so flexible; it offers more freedom than a framework. Libraries are lightweight and contain a wide range of different tools; not only can you build an application, but you can also use the tools outside of that creation. Developers can use the tool to create static sites, desktop applications, and even virtual reality websites and 360 experiences. Developers can also make smaller changes to existing apps and creations, which saves a huge amount of time, making React JS incredibly useful to businesses.
Strong Support and Resources
One of the major advantages of React JS is that it has substantial backing in the form of resources and support – namely, from Facebook. React JS is used across Instagram and Facebook in both website and app form, and there are over 50,000 React JS contributors in the production environment. This means that there is plenty of support and resources available and any changes are automatically updated and replaced with the new specifications. This keeps the developers ahead of changes and allows them to work more quickly.
In addition to support from Facebook, React JS also has strong support from the community and is the option of choice for many Fortune 500 companies. Support and answers are readily available, and this also applies to components. The popularity of React JS means that there are plenty of libraries already available on the web; once again, this is a huge time saver.
React JS, however, minimizes the changes which are made to the DOM by focusing only on what is necessary. Rather than follow tradition and update the entire page to reflect the new state, React JS creates a copy of the original DOM. This is known as the “Virtual DOM” and is used to monitor the values of each component’s state. When a single component changes, such as a user making a comment, React JS can compare the condition of the existing DOM state with what the new DOM should look like. It then goes on to find the easiest, fastest and cheapest way to update the original DOM.
Not only does this speed up the entire process, but it also ensures that your layout remains intact, as only the required changes are made. React can alter and change state’s automatically, as soon as the data gets updated, and this change occurs in the memory – this is faster and more efficient, reducing the strain on the CPU and helping to preserve the battery. This means you can enjoy improved performance with reduced strain on the system.
Ease of Testing
User testing is an essential part of any developer’s job, and the design and construction of React JS make it user friendly and easy to test, largely due to the lack of configuration required for testing. Testing can also be carried out using the node command line rather than in a browser, which speeds up the process significantly. It allows multiple test suites to be run at one time, which is a real time saver when you have a big project. The prevalence of React JS means that there are also plenty of frameworks that allow you to test.
