React Js Add item from array to another array where is same id:In React.js, you can add an item from one array to another when they share the same ID by using functions like map and find. First, you map through the source array and use find to locate the item with the matching ID in the target array. Once found, you can update its properties or push it into the target array.

How can you use Reactjs to add an item from one array to another array when both items share the same ID?
This React.js code defines two arrays, array1 and array2, each containing objects with an 'id' property. The mergeArrays function is triggered by a button click and merges items from array2 into array1 based on matching IDs. It uses the map function to iterate through array1, and for each item, it searches for a matching item in array2 using find. If a match is found, it merges the properties of both objects. Finally, the merged array is updated in the component's state, and the result is displayed on the webpage when the button is clicked.
Output of Above Example
