If you’re new to ReactJS or just refreshing yourself on the core concepts, this article will give you an introduction to all of React’s fundamentals. We’ll be covering the following topics in this article:
What is React?
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.
React’s popularity today has eclipsed that of all other front-end development frameworks. Here is why:
- Easy creation of dynamic applications
- Improved performance
- Reusable components
- Unidirectional data flow
- Small learning curve
- It can be used for the development of both web and mobile apps
- Dedicated tools for easy debugging
A Simple Component
React components implement a
render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by
A Stateful Component
In addition to taking input data (accessed via
this.props), a component can maintain internal state data (accessed via
this.state). When a component’s state data changes, the rendered markup will be updated by re-invoking
