This question really bothered me for a little while ...

Finally, I didn't understand the requirements , A few minutes late

Random number function from greetings Take a value at random and return

use random() Function is fine , array [Math.floor((Math.random()* array .length))]
You can return the random value of the array , Finally, call show() Just assign a value to the greeting card box

function show(greetingDisplay) {

greetingDisplay.innerText =writeGreeting()
