C default arguments
... double x_out = in.x ? in.x : 3.14;
return f_base(i_out, x_out);
}
Now add a macro, using C's variadic macros. This way users don't have to know they're

away from this in the future.
In the future, we'll likely use ems for type sizing, perhaps rems even, but not for anything else. This is also debatable on fo...
Javascript when to use prototypes
...ultiple Car() instances.
var volvo = new Car(),
saab = new Car();
Now, you know each car will need to drive, turn on, etc. Instead of attaching a method directly to the Car() class (which takes up memory per each instance created), you can attach the methods to the prototype instead (creat...
