• کامپایل سریعتری را فراهم می‌کند (انتشار در انگیولار  9) 
• بررسی type  در قالب‌ها، خیلی بیشتر بهبود یافته است؛ به‌گونه‌ای که می‌توان خطاهای بیشتری را در زمان build گرفت که باعث می‌شود کاربران در زمان runtime به آن خطاها برخورد نکنند (انتشار در انگیولار 9). 
  
• bundle‌های با سایز کوچکتری در مقایسه با سایز bundle‌های کامپایل شده‌ی جاری 
  
• کد‌های تولید شده توسط  Angular compiler، بسیار آسان‌تر، برای خواندن و درک انسان است. 
• آخرین و مهمترین ویژگی مورد علاقه من این است که می‌توان قالب‌ها (templates) را debug کرد. من یقین دارم که این ویژگی توسط تعداد زیادی از توسعه دهندگان مورد توجه قرار خواهد گرفت .
