When you visit a website, what is the first thing you notice? Its appearance, right? Websites can be beautiful and they can be dull as well. But is appearance everything? No, not at all. The most important factor of a website is its performance. This modern era demands high performances from their websites. There could be countless users accessing the same page at the same time.
The website should be strong enough to handle the pressure. It should be fast. It should not take more than usual time to open a web page or do anything on it. It all depends upon how a website is built and what kind of technologies are used in it. React.js is one such technology.
What is React?
Check the following statistics.
This is a list of the most popular web technologies of the year 2019. React is in the second position. Do you know which is the most ‘loved’ web technology? Check the following statistics.
It is none other than react. Apart from being the second most popular and the most loved web technology, react is also the most wanted web technology of the year 2019.
But why? What is the reason for such popularity and demand? Before React, developers were forced to write a lot of code. They have to build complex components and there was no proper reusability. They wanted a framework with which they can break down complex components and they could have enough reusability to complete their projects fastly. React provided all this.
The react is concerned with UI rendering. The fact that React uses virtual DOM instead of the real DOM greatly increases its performance while rendering data. React is way more flexible than other frameworks such as Angular. As mentioned, React’s only concern is UI rendering and to create a proper single-page application, you need other third-party libraries for features such as routing and state-management. You do not need to depend on only one thing. For example, react itself provides an in-built method for state-management, i.e. useState(). But we can also use other libraries for better performance, such as Redux.
