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.

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" }}
```
