Angular 2'den ilham alan, içine gömülü bir <abbr title="Bağımlılık enjeksiyonu: Dependency Injection">bağımlılık enjeksiyonu</abbr> sistemi var. Bildiğim diğer tüm bağımlılık enjeksiyonu sistemlerinde olduğu gibi"<abbr title="Injectable: dependency injection sistemi tarafından enjekte edilecek dependency (bağımlılık)">bağımlılık</abbr>"ları önceden kaydetmenizi gerektiriyor. Böylece projeyi daha detaylı hale getiriyor ve kod tekrarını da arttırıyor....
