Let's welcome Custom Hook to solve the problem. So, you shouldn't keep this tightly coupled with any components. But think about it, you may need this countdown calculation elsewhere in your app in the future. Please note we can do the entire countdown computation inside CountdownTimer or ShowCount components.

ExpiredNotice: A component that shows the warning text saying the timer is expired and what action to take.

DateTimeDisplay: A reusable presentational component to show the number of days, hours, minutes, and seconds along with its labels.

ShowCount: A component to show the countdown count for days, hours, minutes, and seconds.

CountdownTimer: A parent component that conditionally renders the countdown or the expiry notice.

So, we can separate the responsibilities into the following components, It shows an expiry notice when the countdown expires. The application has a user interface to show the countdown numbers. Please note how we can identify and mark the components. Here goes the design and component breakdown of the countdown application.

Decide on reusable logic that you can isolate and reuse among components, welcome custom hooks.

Decide on the component's state and data to pass as props among the components.

When you are learning React, you need 'Thinking in React'.

Basic State Management using Standard Hooks.

Please note, if you are a newbie to React and planning to follow along with this article, you will learn the concepts like, The image below shows a working example of the app. Once the date and time expire, it will show an expiry notice. We will create a countdown timer that will allow us to set an initial date and time to start the countdown. What could be better than learning it by developing a small but practical application? This article aims to explain the usages of the custom hook in a beginner-friendly manner. However, the practice of writing custom hooks seems to be a bit lesser.

Web developers widely use React's standard hooks like useState, useEffect to manage state within the components.

With the inclusion of functional components and hooks, it is even more potent in reusability, better code organization, and data flow. React(aka ReactJS) is a library that builds declarative and component-based user interfaces.
