Difference between keys and props in React
Keys are not the same as props, only the method of assigning “key” to a component is the same as that of props. Keys are internal to React and can not be accessed from inside of the component like props. Therefore, we can use the same value we have assigned to the Key for any other prop we are passing to the Component.
ReactJS Keys
React JS keys are a way of providing a unique identity to each item while creating the React JS Lists so that React can identify the element to be processed.
