React Js Get Input field Value using ref or id
React Js Get Input field Value using ref or id:To get the value of an input field in React using either ref or id, you can follow these steps.
With the ref approach, you create a ref using the useRef hook, assign it to the input element, and then access the value through the ref's current property.
Alternatively, with the id approach, you assign a unique id to the input element, and then use the document.getElementById method to retrieve the element and access its value.
Both methods allow you to access the input field value in React, but using refs is recommended as it follows React's unidirectional data flow paradigm.
