Let’s take a look at an Instagram webpage example, entirely built using React, to get a better understanding of how React works. As the illustration shows, React divides the UI into multiple components, which makes the code easier to debug. This way, each component has its property and function
Now that we know what React is let’s move on and see why React is the most popular front-end library for web application development.
Let us look at the essential and most demanding features :
2. Virtual Document Object Model
React make an in-memory data structure cache, then it computes the difference between the previous DOM and the new one and then updates the changes or mutations performed. Thus, it updates only the changes, not the whole application. This helps to increase speed and performance and reduces memory wastage.
React views are used as the state’s functions where the state determines the behavior of the component. Therefore we can make changes to the state and then pass it to a view the ReactJS and then determine the output and the actions, functions, and events. This makes testing and debugging easy.
5. One Way Data Binding
It allows one-way flow of data, i.e. one-way data binding. Due to this feature, there is better control over the application. It makes the application’s state to be contained in specific stores, and therefore all other components remain loosely coupled. This enhances the flexibility and efficiency of the application.
7. Learning Curve
In comparison to other frameworks, the learning curve of React is low. Beginners having basic programming language can also learn to React easily
React’s popularity today has eclipsed that of all other front-end development frameworks. Here is why:
The above reasons more than justify the popularity of the React library and why it is being adopted by a large number of organizations and businesses. Now let’s familiarize ourselves with React’s features.
Below are the advantages and disadvantages:
If this is your first time building a React app, we covered a lot of ground here. One of the biggest takeaways is that React is different than other libraries because it uses a whole new language called JSX to define what the visuals will look like. We got a very small glimpse of that here when we defined the h1 tag inside the render method.
In future chapters, we’ll spend some time diving deeper into JSX and going beyond the render method as we look at all the important things that make React tick.
