Answer 1

I wonder why would you add a random code which has no relation to your question lol? People are really weird here in the questions section.

However the alert ("some text") calls a pop up box that provides the text which is inside the parentheses.

Answer 2

Alert() in js is basically a text box popup that can display information.
Alert("Hellow world"); will display a hello world pop up

I don't really understand the reason for the linked question.
Is it somehow related to this ?

Hope u have helped and if u have Any more questions let me know :)
