* Creates a function that will process either the `onTrue` or the `onFalse`

* @since v0.8.0
* @category Logic
* @sig (*... -> Boolean) -> (*... -> *) -> (*... -> *) -> (*... -> *)
* @param {Function} condition A predicate function
* @param {Function} onTrue A function to invoke when the `condition` evaluates to a truthy value.
* @param {Function} onFalse A function to invoke when the `condition` evaluates to a falsy value.
* @return {Function} A new function that will process either the `onTrue` or the `onFalse`
