compare.Conditional	cond	Returns one of two arguments depending on the value of the control argument.	functions		docs parent functions	aliases returnType signatures cond any compare.Conditional CONTROL ARG1 ARG2	compare.Conditional compare.Default	/functions/cond

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.

{{ $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.

{{ 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:

{{ cond true "true" (div 1 0) }}
{{ cond false (div 1 0) "false" }}
