## Abubuwan da tsarin ƙirƙira ke maguje

```text
CREATIONAL patterns abstract and control HOW objects are CREATED:
  → instead of directly calling constructors everywhere (rigid, coupled), creational
    patterns make object creation flexible, decoupled, and manageable
→ they help create objects in a way suited to the situation, decoupled from concrete classes
```

## Tsarin ƙirƙira na gida

```text
SINGLETON → ensure only ONE instance of a class (single shared object)
FACTORY METHOD → create objects without specifying the exact class (defer to a method/subclass)
ABSTRACT FACTORY → create FAMILIES of related objects (without specifying concrete classes)
BUILDER → construct complex objects step-by-step (separate construction from representation);
  good for objects with many optional parts/parameters
PROTOTYPE → create new objects by CLONING an existing one (copy a prototype)
```

## Lokaci da dalilin

```text
✓ FACTORY → when creation logic should be centralized/decoupled from concrete classes
✓ BUILDER → when an object has many parameters/optional fields (avoid huge constructors;
  readable step-by-step construction) — very practical
✓ SINGLETON → genuinely-single resources (with caveats — see Singleton)
✓ PROTOTYPE → when cloning is cheaper/easier than creating from scratch
→ use the one that fits the creation problem; they decouple code from concrete creation
```

Samuwar tsarin ƙirƙira yana da mahimmanci domin suna maguje **abubuwan da ke damita da mahimmanci game da ƙirƙirar abubuwa** ta hanyoyin da ke dace, buɗe, da suna yajiye — saboda wannan ilimin ƙira na mahimmanci.

Tsarin ƙirƙira suna tunkalin *yadda ake ƙirƙira abubuwa*, suna sanya bayani da kula da halin ƙirƙira domin sanya shi bashi — wajen waje abubuwa da ba shi tunkalin abin da yake jiya ma.

Samuwar **tsarin ƙirƙira na gida** — **Singleton** (ɗayan sadarwa), **Factory Method** (ƙirƙirar abubuwa ba tare da bayyana class), **Abstract Factory** (ƙirƙirar jama'a na abubuwa masu dangantaka), **Builder** (gina abubuwa masu hadiya a mataki-mataki), da **Prototype** (kwafi abubuwan da ke akwai) — yana rufe kayan aiki don ƙirƙirar abubuwa da ke dace.

Samuwar **lokaci da dalilin** amfani da kowannensu shine ilimin aiki: **Factory** lokacin da ƙirƙira ya kamata a taimaka da sanya daban daban daga class, **Builder** lokacin da abun da yake da yawa ma'amala ko filayen da ba dole ba (guje dila na abubuwan da ba shi kawai — tsarin da ya yi aiki da gaske), **Singleton** don alamu da jiya gida (tare da abubuwan sawarawa), da **Prototype** lokacin da kwafi ya fi saurin ƙirƙira daga gida.

**Builder pattern** musamman yana da aiki gaske don abubuwan da ke damita da yawa ma'amala masu nuni.

Samuwar tsarin ƙirƙira a matsayin gungu, da yadda kowannensu ke tunkalin tsarin ƙirƙira daban-daban, yana taimaka maka ƙirƙira abubuwa ta hanyoyin da ke dace, da shari, da suna yajiye daban daga class.

Tun da ƙirƙirar abubuwa shine abubuwan da ke damita, mahimmanci, da tsarin ƙirƙira suna tunkalin haka ta hanyoyin da ke dace, suna yajiye daban (Factory don yajiya, Builder don abubuwan hadiya, jn.), da tun da samuwar tsarin da lokaci amfani da kowannensu ya shafi rubuta lamurin da ke dace, da tsarin ƙirƙira shine ilimin ƙira na mahimmanci — gungu mahimmanci na tsarin don tunkalin ƙirƙirar abubuwa ta hanyoyin da ke dace, tare da Builder da Factory suke mahimmanci gaske, da ilimin ƙira mahimmanci don ƙirƙira abubuwa ta hanyoyin da suna yajiye, da lamurin da ke dace.
