import ifnot from "if-not";
ifnot(false, console.log, "Hello world!", "second argument!");
ifnot(true, console.log, "this won't be executed!");
// without if-not: look at all the bangs! all the indentation! this is unacceptable!
if(!false) {
console.log("Hello world!", "second argument!");
}
if(!true) {
console.log("this won't be executed");
