Conditional Statements

Conditional statements allow developers to control the flow of a program based on certain conditions. Go provides the standard if, else, and switch statements for handling conditions in a concise and expressive manner.

Code Example

if, elseif, else

If, else if and else are the most straight-forward way of implementing conditionals in Go. This can be achieved by the following syntax.

func AccessControlSwitchCases(role string) int {
    if role == "owner" {
        return 1
    } else if role == "admin" {
        return 2
    } else if role == "user" {
        return 3
    }
    return 0
}

Switch case

Switch statement evaluates an expression and executes the code block associated with the first matching case, offering a concise way to handle multiple conditions without requiring explicit break statements between cases. It is similar to using if-else. However, the values provided in the switch case is compared directly with the possible cases.

func AccessControl(role string) int {
    switch role {
    case "owner":
        return 1
    case "admin":
        return 2
    case "user":
        return 3
    }
    return 0
}
