Why is my program not working?

Question

I created a function named greetings() which alerts the string "Hello" to the windows with the line window.alert("Hello")

The problem is on vs-code

I even called the function but nothing is happening

Answer 1

Don't see why VSCode was rejecting it, it runs as it should in Code Playground, and Chrome (mobile), even built-in browser.

Answer 2

It does show. But in the pop-up.
