React Js Remove Item from array by Index
React Js Remove Item from array by Index:To remove an item from an array by index in ReactJS, use the splice() method or the spread operator with filter(). With splice(), array.splice(index, 1) removes the item at the given index. Alternatively, using the spread operator, create a new array excluding the item: const newArray = array.filter((item, i) => i !== index). Then, update the state with the modified array. Ensure you don't directly mutate the state; instead, use setState() or state management tools like Redux. Remember to consider performance implications for large arrays due to array copying when using the spread operator.

How can you remove an item from an array by its index using Reactjs?
This React.js script demonstrates how to remove an item from an array by its index. It initializes a state variable 'items' with an array of items. The 'removeItemByIndex' function takes an index and creates a copy of the 'items' array. It then uses 'splice' to remove the item at the specified index and updates the state with the modified array. The UI displays a list of items with 'Remove' buttons. When a button is clicked, it triggers the removal function for that index. The result is a dynamically updated list with items removed upon button clicks.
