What are controlled and uncontrolled components in reactjs
In React, "controlled" and "uncontrolled" components refer to two different approaches for managing form elements and their values.
A controlled component is a form element, like an input or textarea, whose value is controlled entirely by React's state. When the value of the input changes, the component's state is updated, and the new value is propagated to the input as a prop. This approach allows React to have full control over the component's behavior, making it easy to manage and manipulate form data.
An uncontrolled component, on the other hand, is a form element whose value is managed by the DOM itself. React doesn't control the value directly; instead, you rely on the DOM to manage and access the input's value. This can be useful in certain scenarios where you want to integrate React with existing code or when you need direct access to the DOM element's value.
