iff

any iff(any, any, any)

The first expression is considered a predicate, that is, an expression that evaluates to either true or false.

Depending on the result of evaluating the predicate expression, the iff function returns the evaluation of its second expression if true, otherwise it returns the evaluation of its third expression.

Examples

Given	Expression	Result
	iff(`true`, `true`, `false`)	true
	iff(`false`, `true`, `false`)	false
{ "eval": true, "true": "truthy", "false": "falsy" }	iff(eval, true, false)	"truthy"
{ "eval": false, "true": "truthy", "false": "falsy" }	iff(eval, true, false)	"falsy"
