Order Processing Function Javascript Solution

This script is designed to handle a list of orders in a shopping system. It takes in an array of orders, an order ID, and a state. The function then processes the list based on the given state and order ID. If the state is 'Processing', it updates the state of the order with the given ID to 'Processing'. If the state is not 'Processing', it removes the order with the given ID from the list.

Here is the Order Processing Function Javascript Solution from HackerRank using CodeRankGPT:

The function 'processOrderList' uses JavaScript's map and filter functions to process the order list. If the state is 'Processing', it uses the map function to iterate over each order in the list and returns a new array where the state of the order with the given ID is updated to 'Processing'. If the state is not 'Processing', it uses the filter function to create a new array that does not include the order with the given ID.


use strict';

function processOrderList(orderList, orderId, state) {
    return state === 'Processing' ?
      orderList.map(item => ({
        ...item,
        state: item.id === orderId ? 'Processing' : item.state
      })) :
      orderList.filter(item => item.id !== orderId);
}
