Instead of changing the code of the snippet, consider creating another JS implementation.

Other implementations

items = append([]T{x}, items...)

items = append(items, x)
copy(items[1:], items)
items[0] = x

items = [x, items]

items.insert(0,x);

items.unshift(x)

items.prepend(x)

unshift @items, $x

items = [x] + items

#include <list>

items.emplace_front(x);

#include <list>

items.push_front(x);

items = [x, ...items];

use std::collections::VecDeque;

items.push_front(x);

items2 = x : items
