Value assignment after a closing curly brace? Why does this syntax work?

For context: I come from a heavy Javascript background, so seeing an assignment occur immediately after a closing curly brace kind of boggles my mind. The linter inside my brain is short-circuiting! :P

I'm interested to know if anyone has insight into why this works? Is this only possible with Properties? Thanks!

namespace Treehouse.CodeChallenges
{
    class CountDown
    {
        public int StartAt { get; private set; } = 10; // <-- Why is this valid syntax?
    }
}

When creating the property you can give it a default value when you create it. This can be good when you need a starting value and then later subtracting or adding to that within the class and subclasses. This way you can just go back to the property and change the value in order to change the program, rather than go through all methods.

To answer why it works after the curly bracers is because the code isn't ended yet, since the semicolon comes after 10.

class Bottle
{
    public int Quantity { get; set; } = 30; // Setting the default value to 30
}

class Program
{
    static void Main()
    {
        Bottle bottle = new Bottle();

        Console.WriteLine(bottle.Quantity); // Will show the default value of 30.

       bottle.Quantity *= 2;
        Console.WriteLine(med.Quantity); // Will multiply the default vaule by 2, showing 60.
    }
}
