What is it

// comparison operator
if condition == "true" { 
  ...
}

// not equal to
if condition != "true" { 
  ...
}

// logical NOT operator
if !condition == "true" {
  ...
}

// logical AND
if ( a && b ) {
  fmt.Printf("Condition is true")
}

// logical OR
if ( a || b ) {
  fmt.Printf("Condition is true")
}

if, else if, else

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")
}

No Ternary in Go

There is no ternary syntax in Go.

• https://go.dev/doc/faq#Does_Go_have_a_ternary_form

if-else will have to do.

if expr {
  n = someval
} else {
  n = anotherval
}

Alternative

With below function, we can use syntax of If(condition, value_true, value_false) which provides syntax close to ternary.

func If[T any](cond bool, vtrue, vfalse T) T {
  if cond {
    return vtrue
  }
  return vfalse
}
