Can anyone please show me how to use the .push() method for an array?

Ask the user to input names of people they would like to invite to a dinner party.
Each name should be added to an array.
The user can only invite a maximum of ten people. If they try to add more than 10 names, the program should state, “You have already added 10 people to your guest list.”
The program should then output the list.

I am trying to solve this task, I am not sure if I am doing it properly. I am a beginner so I will appreciate any help or hints.

{
    let list = [];
    list.length = 10
    while(true){
      let input = prompt("Add a guest");
      if(input <= 10 || input == null){ 
        break;  //arr.slice(0,10) 
      }
      list.push(String(input));
      console.log(list);
    }
}
