• عدم حذف تگ‌ها ، گاها برنامه نویس‌ها از تگ هایی چون Bold,italic,underline,color استفاده می‌کنند که معدود برنامه‌هایی آن را پشتیبانی کرده و تلویزیون و پلیرها هم که اصلا پشتیبانی نمی‌کنند و باعث میشود که متن روی تلویزیون مثل کد html ظاهر شود
• بعضی جملات دوبار روی صفحه ظاهر می‌شوند.
• تنها یک فایل را در هر زمان تبدیل می‌کند. مثلا اگر یک سریال چند قسمته داشته باشید، برای هر قسمت باید زیرنویس را انتخاب کرده و تبدیل کنید، در صورتی که میتوان دستور داد تمام زیرنویس‌های داخل دایرکتوری را تبدیل کرد یا چند زیرنویس را برای این منظور انتخاب کرد.

به ازای هر آیتمی که در شیء بازگشتی وجود دارد، با استفاد از متد each در jQuery یک li ایجاد می‌کنیم. همان طور که می‌بینید کلیه خواص، به شکل Fluent قابل اضافه شدن می‌باشد. سپس برای li یک رویداد کلیک که در صورت وقوع، متد FillData را با شناسه فید کلیک شده فراخوانی می‌کند و در آخر li را به المنت ul اضافه می‌کنیم.

برای هر کلیک هم مانند مثال بالا api را با شناسه‌ی فید مربوطه فراخوانی کرده و به ازای هر آیتم، یک سطر ایجاد می‌کنیم.

Stack

این ساختمان داده، داخل Memory پیاده سازی شده است و تعدادی از متغیرهایی را که ما داخل کد ایجاد میکنیم، در این نوع ساختمان داده از Memory نگهداری میشوند.

شرط قرار گرفتن مقدار یک متغیر داخل Stack این است که متغیر از نوع Value Type باشد. در زبان #C، بطور کلی Struct و Enum‌ها Value Type هستند و بصورت پیشفرض داخل Stack قرار میگیرند. تمامی ValueType‌ها در #C، بطور implicit از System.ValueType ارث بری میکنند.

Type‌های زیر، Value Type‌های پیشفرض تعریف شده‌ی در زبان #C هستند که به آن‌ها Simple Type نیز گفته میشوند:
