Javascript 以相反的顺序显示分页列索引

我在显示分页数据时遇到了一个问题.默认情况下，程序将每页显示5行，在列索引期间，它将显示从1开始的行号，然后在第二页上，行号将从6开始.

idx: 1 | name: John
idx: 2 | name: Doe
idx: 3 | name: John
idx: 4 | name: Doe
idx: 5 | name: John

page = 2:个个

idx: 6 | name: Tim
idx: 7 | name: John
idx: 8 | name: Doe
idx: 9 | name: John
idx: 10 | name: Doe

Code:个

const names = [
    "John",
    "Doe",
    "John",
    "Doe",
    "John",
    "Tim",
    "John",
    "Doe",
    "John",
    "Doe",
];

let page = 1;
let limit = 5;
let totalCount = names.length || 0;

function pagination(array, page, limit) {
    return array.slice((page - 1) * limit, page * limit);
}

const newArray = pagination(names, page, limit);

newArray.forEach((item, index) => {
    const idx = (page - 1) * limit + (index + 1);
    console.log("idx:", idx, "|", "name:", item);
});

当我将第2页更改为2页时，它将在第二页上显示从第6行开始.

但问题是，我希望以相反的顺序显示行索引，如下所示: 第一行应该将索引显示为10，在第二页上，索引从5开始.我如何实现这一点？这是什么公式？

idx: 10 | name: John
idx: 9 | name: Doe
idx: 8 | name: John
idx: 7 | name: Doe
idx: 6 | name: John

page = 2:个个

idx: 5 | name: Tim
idx: 4 | name: John
idx: 3 | name: Doe
idx: 2 | name: John
idx: 1 | name: Doe
