How do I code html with the below? I get stuck and the code doesn't run.

Compulsory Task $1$

Follow these steps:

Create a new JavaScript file in your task folder called guestList.js$.$

Ask the user to input the names of people they would like to invite to a

dinner party.

Each name should be added to an array.

When the user inputs the eleventh name, the program should return a

message in the prompt box which reads: "You can only add a maximum

of $10$ people to your guest list. Would you like to replace someone on the

list with the last person you entered? yes$/$no: $"$

If the user enters "yes", the program should ask the user to$,$ "Please enter

the name of the person you would like to replace". Note: The program

should replace a person from the first $10$ guests with the $11$ th person at

the index position of the person they select to replace. The updated list

with the replacement should then be displayed.

If the user enters $"$no$",$ the program should only display the guest list

consisting of the first $10$ people that the user originally input.

Ensure that the program handles all variants of yes$/$no responses from

the user meaning YES, yes, NO$,$ no$,$ etc. should all be recognised.

Display the guest$-$list that is output on a single line with each name

separated by a comma.
