This code snippet demonstrates how to get the value of an input field in React.js. It utilizes the useState hook from React to manage the state of the inputValue variable.
Initially, inputValue is set to an empty string. The handleChange function is triggered whenever the value of the input field changes. It updates the inputValue state with the new value entered by the user.
The input element has the value attribute set to {inputValue}, which ensures that the input field reflects the current value of inputValue.
