When writing React applications, it’s important to remember that the presentation component should never implement application logic. While it is OK to implement user interaction and send user input to other components, you should not call the parent API directly. Instead, give the child a reference to the parent function and it will invoke that function without knowing what it is called. In this way, you can avoid creating redundant components that share the same name. You can even reuse components in different areas of your app.

Besides this, React comes with a syntax extension called JSX that helps you write custom components for your applications. These components are essential for building high-volume applications, but frequent updates can be a pain. However, this is a problem that React aims to solve with its component reusability feature. This feature allows you to create components that are reusable, saving you the hassle of updating the whole app.

The virtual DOM is an essential part of React, which makes keeping track of updates in real-time easy. As it deals only with the view layer of web pages, it is easy to learn and use. Learning the language is straightforward, making it an ideal choice for beginners. There are also many free tutorials available online. It is recommended that you read up on React and learn a little about JSX before diving in.
