React Js Remove/Delete item from array by id
React Js Remove/Delete Item From Array By Id: To remove an item from an array in React.js using the splice method, you can follow these steps. First, find the index of the item you want to remove based on its unique ID.
Next, create a copy of the array using the spread operator. Then, use splice to remove the item from the copied array by specifying the index and the number of elements to be removed (in this case, it will be 1).
Finally, update the state of the array using the copied array without the removed item. This ensures the component re-renders with the updated array.

How can I remove/delete an item from an array in React.js based on its ID?
This React.js code demonstrates how to remove or delete an item from an array based on its ID. The code uses the useState hook to create a state variable called items, which holds an array of objects representing countries.
The removeItem function takes an ID as a parameter, finds the index of the item with that ID in the items array, and if found, creates a copy of the array using the spread operator.
It then uses the splice method to remove the item from the copied array. Finally, the setItems function is called to update the state with the updated array.
The rendered JSX displays the list of items and provides a "Remove" button for each item, which triggers the removeItem function when clicked
