//higher order function is just a function that take other function as a parameter
//example forEach
function repeater(fn){
fn(); fn(); fn();
}
function sayHello(){
console.log("Hello There!")
}
repeater(sayHello);//at console Hello There 3 times._
//repeater is higher order function that take sayHello as function parameter.
