React Js Input Field Length Validation
React Js Input Field Length Validation:React JS input field length validation refers to the process of checking the length of user input in a form field and validating it according to certain criteria.
This validation ensures that the input meets the required length restrictions or limits. In React, this can be achieved by using event handlers and state management.
By monitoring the input field's value, developers can compare its length to predefined conditions and display appropriate error messages or prevent form submission if the input is invalid

How can I implement input field length validation in React.js?
The provided code is a React.js component that implements input field length validation. It uses the useState hook to manage the component's state.
When the input value changes, the handleInputChange function is called, updating the inputValue state. If the length of the input value is between 10 and 15 characters (inclusive), the isValid state is set to an empty string.
Otherwise, the isValid state is set to a message indicating that the input length must be either longer than 5 or shorter than 10.
The input element displays the current value, and a small element below it displays the validation message if applicable
