Go Has No Ternary

The ternary operator is common in programming — syntactic sugar for a single control flow. JavaScript has it, Ruby has it, Python has it. Go does not.

You can mimic it through a map-tuple trick:

a := (map[bool]string{true: "its true", false: "its false"})[expression]

It works, but it’s obfuscated and not idiomatic Go. Plain control flow is faster to read and easier to reason about:

var a string
if expression {
    a = "its true"
} else {
    a = "its false"
}

Or, if one branch is the default:

a := "its true"
if !expression {
    a = "its false"
}

Go’s omission isn’t oversight. It’s a constraint that nudges you toward the version your future self can read at a glance.
