Question

I want to define a property to some namespace depending on another property. The following is my attempt to assign someNameSpace.x2 based on someNameSpace.x1:

someNameSpace = {
  x1: 100,
  x2: x1 * 0.5,
};

but it fails. What is the correct way to do this?

Answer 1

You can’t do that because x1 hasn’t been defined yet in the scope.

someNameSpace = { x1 : 100 };
someNameSpace.x2 = someNameSpace.x1 * 0.5;
