Where did ReactJS come from?
ReactJS was created in 2011, with its flagship application being the foundation of the first Facebook app. Prior to ReactJS developers primarily used jQuery and a few other UI interfaces to create the appropriate framework for their websites. However, frameworks of this nature are usually complicated and hard to explain. Thus, it was much more difficult for new developers and even new members to software development teams to get the hang of the programming structure.
ReactJS is different in that it is component-based. This means it does not make assumptions about the rest of a platform’s technology stack. This makes it possible to develop new features to React without rewriting the existing code. This is new because it separates the systems so that they are not always reacting to the entire program; rather, each component has its own set of reactions. This helps minimize bugs and issues, as well as helping to isolate problems without ripping apart the whole code. Considering Facebook was the intuitive, first-generation parent company for ReactJS and still is, it has always had the advantage of rising in success with its creator.
Why Use ReactJS?
There are many different reasons that ReactJS, even nine years after it was first created, is still being downloaded in the millions, on a daily basis. Here is a description of the framework’s best features to explain what ReactJS is used for:
ReactJS Virtual DOM
Thankfully, Virtual DOM helps rectify this situation by creating a copy of the DOM. This is called Virtual Dom. This copy is compared with the normal DOM and the only elements that are re-rendered are those which are changed. This system is less invasive and it takes less computing power, which results in faster loading time and mitigates any bugs or rendering issues that may arise.
Additionally, ReactJS can render on the server using Node and power mobile apps using React Native. Therefore, they can work together, as well as being two similarly functioning solutions for desktop and mobile-based applications.
Pros and Cons of ReactJs
Pros of ReactJS
-The Ability to Repeat Code.
Before ReactJS, a developer would have to use straight code, rewriting it over and over again, for different aspects of the same projects (and other projects). However, with ReactJS came the concept of modular code. Modular code is a part of the React JS library that enables developers to use separate modular components to create different aspects of code applications. Have a look at the example. Here’s the component to describe the look and behavior of the link.
And now you can use the link component in any part of the application code. Let’s take the social media links for example.
- Available in Different Languages.
- Portuguese (Brazil)
- Simplified Chinese
- Traditional Chinese
However, even this selection of languages is not the end of the platform’s future communication plans. There are over two-dozen other languages of content that are currently being produced or are actively seeking contributors.
- ReactJS is Updated Frequently.
ReactJS is updated frequently, with a talented, global team helping to make it as universally useful as possible. Therefore, a developer of any level of experience can be sure they are working with the most updated system ReactJS has to offer. This is important, especially for long-running successful frameworks, such as ReactJS and React Native because a constant update is better on the system. Instead of having a few major updates, there are many smaller updates, which help developers manage the changes and debug their platforms in a manageable way.
Cons of ReactJS
- SEO Issues.
Remembering that ReactJS is a digital child of Facebook, the fact that many find the framework’s extra SEO steps annoying is ironic. While it is not bad at SEO, ReactJS certainly isn’t the best. In 2014, Google webmasters confirmed that the search engine’s crawlers cannot properly index dynamic content. Since ReactJS is built around the idea of adding dynamic content to a website, this is disappointing. Now, that doesn't mean that a website with the ReactJS framework will not be indexed. But, it does mean that there are a few extra tests to make sure Google (and other search engines) crawlers notice the site.
- There is a Learning Curve.
What Types of Projects is ReactJS Ideal For?
ReactJS is perfect for development in various industries, from real estate web development to blockchain development. It is used to create and maintain thousands of popular websites and social networking platforms. Here is a list of some of the most famous:
- Facebook (Obviously)
Basically, this list of just the top-rated websites that use ReactJS is overwhelming. When the average person looks at this list, alone, though, they notice the range of seemingly unrelated websites and platforms that use ReactJS. Indeed, this is an amazing feat, considering the list ranges from banking applications to social networks, and from personal BnBs to cloud storage providers. However, what a developer sees when they look at this list is even more enlightening. From this list, developers can get a good picture of exactly what the single-page application framework can accomplish.
