Time Format Converter using ReactJS

In this article, we will develop a Time Format Converter Project application using the ReactJS library. A Time Format Converter is a React-based tool that allows users to convert between 12-hour and 24-hour time formats. It validates input, performs the conversion, and displays the result or error message in a user-friendly interface. In this application, we will use the Functional-based components and various hooks to manage the state of the application. Also, we will style the application with different CSS properties and effects. In this application, the user needs to select the conversion format give the input time, and get the results in just one click.

Example:

The user can select the Time Conversion Format as (24-Hour to 12-Hour). 
Then, the user can specify the time as = 22.56. When the user clicks on the
Convert Button, the Result will be: Time in 12 Hour Format is: 10:56 PM.

Approach

For developing the Time Format Converter application, first the user needs to choose the Conversion format, the user can select the conversion format from the drop-down list. After selecting the conversion format, the user needs to enter the time as per the selected format. The field is been validated with the particular time range. For example, when the user selects the conversion of 12-Hours to 24-Hours then, the user can only give the input till midnight/PM. So, overall the proper validation of time values is been done. In converter.jsx file we use React’s useState hook to manage four pieces of state: input time, output time, error message, and selected conversion format (24-hour to 12-hour or vice versa). Conversion Logic: The convertFunction handles the time conversion based on the selected format. It validates input, performs the conversion, and updates state with the result. It handles both 12-hour to 24-hour and 24-hour to 12-hour conversions. UI Elements: The code renders a simple UI with a title, input field for time, a dropdown for format selection, and a Convert button. Error messages and converted time are displayed conditionally based on state. User Interaction: When the Convert button is clicked, it triggers the convertFunction, which performs the conversion and displays the result or an error message if the input is invalid. Users can select the conversion format and enter a time in the specified format. We have styled the application using the CSS classes and properties. This makes the application more attractive interactive and user-friendly for usage....
