+title: compare.Conditional
+description: Returns one of two arguments depending on the value of the control argument.

+
+The CONTROL argument is a boolean value that indicates whether the function should return ARG1 or ARG2. If CONTROL is `true`, the function returns ARG1. Otherwise, the function returns ARG2.
+
+```go-html-template
+{{ $qty := 42 }}
+{{ cond (le $qty 3) "few" "many" }} → many
+```
+
+The CONTROL argument must be either `true` or `false`. To cast a non-boolean value to boolean, pass it through the `not` operator twice.
+
+```go-html-template
+{{ cond (42 | not | not) "truthy" "falsy" }} → truthy
+{{ cond ("" | not | not) "truthy" "falsy" }} → falsy
+```
+
+{{% note %}}
+Unlike [ternary operators] in other languages, the `cond` function does not perform [short-circuit evaluation]. The function evaluates both ARG1 and ARG2, regardless of the CONTROL value.

+{{% /note %}}
+
+Due to the absence of short-circuit evaluation, these examples throw an error:
+
+```go-html-template
+{{ cond true "true" (div 1 0) }}
+{{ cond false (div 1 0) "false" }}
+```
