Why are installed modules not showing up on the Modules/Extensions page?
Installed vqmod. I start to install modules and update in "modifier", but the module does not appear on the Modules/Extensions page. What could be the problem ?
Thank you.

Answer 1

function addUser() {
    let name = prompt('Введите имя пользователя');
    arr[arr.length] = name;
    return arr.sort();
}
let arr = ['Тимур','Саша','Данил','Паша','Вадим'];
console.log(addUser());
/*
name = 'Иван';
console.log() = Array(6) [ "Вадим", "Данил", "Иван", "Паша", "Саша", "Тимур" ]
*/
