Advanced State Management in React Using Redux Toolkit

Modify migrations to include indexes:

   Schema::table('users', function (Blueprint $table) {
       $table->index('email'); // Single-column index
   });

Ensure middleware executes in the correct order using assertions or logs.

• Always verify middleware assignment with route:list.
• Debug middleware execution using logs and condition checks.
• Use priority settings in Kernel.php to resolve execution conflicts.
• Test middleware in isolation to ensure logic behaves as expected.

In a controller, pass data to a view:

   namespace App\Http\Controllers;

   class ExampleController extends Controller
   {
       public function index()
       {
           $userPreferences = [
               'notifications' => true,
               'language' => 'en',
           ];

           return view('example.index', compact('userPreferences'));
       }
   }

• Max Uploads: Limits the number of files a user can upload.
• API Rate Limit: Defines the number of API requests allowed per minute.
• Feature Toggles: Manages the state of application features.

  // app.js
  const { add, subtract } = require('./math.js');

  console.log(add(5, 3)); // Output: 8
  console.log(subtract(5, 3)); // Output: 2

Here, the require function is used to import the math.js module, and the exported functions are accessed from the returned object.

import React from 'react';

function ItemList({ items }) {
  return (
    <>
      {items.map(item => (
        <div key={item.id}>{item.name}</div>
      ))}
    </>
  );
}

For very large lists, consider using windowing libraries like react-window to only render a subset of the list items that are currently visible.

• Grow the Array:

Grow the RAID array to include the new disk:

A simple inventory system that can add, remove, and use items.

using System.Collections.Generic;
using UnityEngine;

public class Inventory : MonoBehaviour
{
    public List<Item> items = new List<Item>();
    public int capacity = 20;

    public bool AddItem(Item item)
    {
        if (items.Count >= capacity)
        {
            Debug.Log("Inventory is full!");
            return false;
        }

        if (item.isStackable)
        {
            Item existingItem = items.Find(i => i.itemName == item.itemName);
            if (existingItem != null)
            {
                // Stack logic (if needed)
                Debug.Log($"Stacking {item.itemName}");
                return true;
            }
        }

        items.Add(item);
        Debug.Log($"{item.itemName} added to inventory.");
        return true;
    }

    public void RemoveItem(Item item)
    {
        if (items.Contains(item))
        {
            items.Remove(item);
            Debug.Log($"{item.itemName} removed from inventory.");
        }
    }

    public void UseItem(Item item)
    {
        if (items.Contains(item))
        {
            item.Use();
        }
    }
}

mysql -u your_username -p your_database_name < backup.sql

• backup.sql: The SQL file containing the exported data.

Performance Schema is enabled by default in MySQL 5.6 and later. To verify it's enabled, run the following query:

SHOW VARIABLES LIKE 'performance_schema';

• A MySQL server installed and running.
• Access to the MySQL command-line client or a graphical tool like MySQL Workbench.
• Basic knowledge of SQL queries.

First, log into your MySQL server using the MySQL command-line client or a graphical tool. For the command-line client, use the following command:

• Create a New Model

  php artisan make:model ModelName
