2:25 [Ctrl] + [/] is a better commenting hotkey, albeit the one in the video is good to know b/c it is used in other Microsoft platforms such as SSMS.

var names = new List() { "Kevin", "Joseph", "Raul", "Marco" };
names.Add("Sophia");
names.Add("Lucy"); // add bucket
Console.WriteLine(names[names.Count-1]); // last element
Console.WriteLine(names[^1]); // count from the back.
Console.WriteLine();
foreach (var name in names[2..4]) // ranges
{
Console.WriteLine(name);
}
Console.WriteLine();
var people = new string[] { "Kevin", "Joseph", "Raul", "Marco" }; // array
people = [..people, "Sophia", "Lucy"]; // new bucket
people.ToList().ForEach(x => Console.WriteLine(x));

[@hipertracker]

names[^2] looks weird, names [-2] is more cleaner
