React js Handle Input Change
React js Handle Input Change:In Reactjs, handling input change involves creating a function that responds to user input in form fields like text boxes. Typically, you set up a state variable to hold the input's current value. When the input changes, the function updates this state using the setState or useState hook. This triggers a re-render, displaying the updated value. Developers can then access and use this value in their application logic, enabling dynamic interactions and data-driven components. Handling input change is crucial for building responsive and interactive user interfaces in React.

How can you handle input change events in Reactjs?
In this React js code snippet, a functional component named "App" manages a form's input fields using the "useState" hook. It initializes "formData" with empty name, email, and gender fields. The "handleInputChange" function is bound to input elements' "onChange" events and updates "formData" by spreading its current state and modifying the corresponding field based on the input's "name" and "value." The component renders text inputs for name and email, a select input for gender, and displays the form data below. When users interact with inputs, the displayed data updates dynamically, demonstrating controlled form handling in React.
