Interface of object parameter with default value and default property

Hope this helps If you are destructuring the second parameter, you can specify the type of any of the properties but you can't specify the type of the parameter you destructured because there's no binding for it (e.g. there's no variable that is actually a ReadCsvConfig). You can do a type cast on the {} expression for the default value with:
function read_csv (filePath:string,{
    index_col=false,
    delimiter=',',
    header=0,
    dataType='number'
}={} as ReadCsvConfig){
...
}

C# 4 default parameter values: How to assign a default DateTime/object value?

With these it helps DateTime cannot be used as a constant but you could make it a nullable type (DateTime?) instead.
Give the DateTime? a default value of null, and if it is set to null at the start of your function, then you can initialize it to any value you want.
static void test(DateTime? dt = null)
{
    if (dt == null)
    {
        dt = new DateTime(1981, 03, 01);
    }

    //...
}
test(dt: new DateTime(2010, 03, 01));
test();

it fixes the issue
If I want every vehicle that inherits from that interface to have a default color of "Red" how could I achieve this?

Use the type parameter of the object in a default interface method

I hope this helps . You're declaring an anonymous inner class that implements the Codec interface.
return new Codec<F,E>() {
    public E encode(F obj) { return codec2.encode(c.encode(obj)); }
    public F decode(E obj) { return c.decode(codec2.decode(obj)); }
};
public E encode(F obj) {
    return codec2.encode(Codec.this.encode(obj));
}

public F decode(E obj) {
    return Codec.this.decode(codec2.decode(obj));
}
