Go by Example: If/Else

Branching with `if` and `else` in Go is straight-forward.
	package main
	import "fmt"
	func main() {
Here’s a basic example.	if 7%2 == 0 { fmt.Println("7 is even") } else { fmt.Println("7 is odd") }
You can have an `if` statement without an else.	if 8%4 == 0 { fmt.Println("8 is divisible by 4") }
A statement can precede conditionals; any variables declared in this statement are available in all branches.	if num := 9; num < 0 { fmt.Println(num, "is negative") } else if num < 10 { fmt.Println(num, "has 1 digit") } else { fmt.Println(num, "has multiple digits") } }
Note that you don’t need parentheses around conditions in Go, but that the brackets are required.

	$ go run if-else.go 7 is odd 8 is divisible by 4 9 has 1 digit
There is no ternary if in Go, so you’ll need to use a full `if` statement even for basic conditions.
