In Go programming language, unless is not a built-in keyword. However, you can achieve the same functionality using the if statement with a negated condition.
The following code shows an example of using unless in Go:
num := 10
unless num == 5 {
fmt.Println("num is not 5")
}
The above code can be converted to use an if statement with a negated condition as shown below:
num := 10
if !(num == 5) {
fmt.Println("num is not 5")
}
In this example, the if statement checks if the condition !(num == 5) is true, and if it is, then it proceeds to execute the code in the block. This is equivalent to an unless statement, as it executes the code block only if the condition is false.
