## Examples

### Using structCount as a function

Pass a structure as an argument to the function.

[Run Example](https://try.boxlang.io/?code=eJwrLU4tUrBVqFbg4vR0UbBSMNTh4nTzDAoO8XP0dQXylTwS85SAYj6OCKHg%2FJx8kJivf5gnRKAksUghPLGoWImr1pqrvCizJNWlNLdAQ6G4pKg0ucQ5vzSvREOhFGSVpoKmNRcA4RsgBA%3D%3D)

```java
user = { 
	ID : 1,
	FIRSTNAME : "Han",
	LASTNAME : "Solo",
	MOVIE : "Star Wars"
};
writeDump( structCount( user ) );

```

Result: 4

### Using structCount as a Member Function

Having a reference of a structure as a variable, use the dot notation to get a key count on it using a member function.

[Run Example](https://try.boxlang.io/?code=eJwrLU4tUrBVqFbg4vR0UbBSMNTh4nTzDAoO8XP0dQXylTwS85SAYj6OCKHg%2FJx8kJivf5gnRKAksUghPLGoWImr1pqrvCizJNWlNLdAQ6EUaLpecn5pXomGpoKmNRcA%2FjQdbQ%3D%3D)

```java
user = { 
	ID : 1,
	FIRSTNAME : "Han",
	LASTNAME : "Solo",
	MOVIE : "Star Wars"
};
writeDump( user.count() );

```

Result: 4
