Description
Study on Dependency Injection Scopes.
# 🎯Scopes
### 🔄 1. Singleton Scope
- Creates one single instance for the entire application lifecycle;
- All consumers use the same instance;
- Suitable for stateful services or heavy resources like databases, caches, etc.
### 🌱 2. Transient Scope
- Creates a new instance every time the dependency is requested;
- Each consumer gets a different instance;
- Ideal for stateless or short-lived services.
### 🌐 3. Scoped Scope
- Creates a new instance per request (e.g., one instance per HTTP request);
- Same instance is shared across the request but discarded after it ends;
- Useful for user-specific services in web applications.

# ✅Dependency Injection Lifecycle Scopes
| **Scope** | **Instance Creation** | **Sharing** | **Use Case** |
|----------------|-------------------------------------------------|---------------------------------|----------------------------------|
| **Singleton** | Once for the entire application lifecycle | Same instance for all consumers | Logging, Cache, Configurations |
| **Transient** | A new instance every time it's requested | Different instance for each call | Stateless services, Helpers |
| **Scoped** | Once per request (e.g., per HTTP request) | Same instance within the request | User-related services (Web apps) |
