## Function Names Verb-Noun

Functions do things. Action verbs make purpose clear.

**Incorrect (vague names):**

```go
func user() { }           // Noun only
func userData() { }       // Noun only
func doSomething() { }    // Vague
func handleStuff() { }    // Vague
func manager() { }        // Noun only
```

**Correct (action verbs):**

```go
func GetUser() { }
func CreateUserAccount() { }
func ValidateEmailFormat() { }
func CalculateTotalPrice() { }
func SendConfirmationEmail() { }
func ConvertCurrencyToUSD() { }
```
