JavaScript library for defining types and their properties with support for wrapping/unwrapping and serialization/deserialization.

function copyProps (from, to) {
  Object.getOwnPropertyNames(from).forEach(function (name) {
    const descriptor = Object.getOwnPropertyDescriptor(from, name);

  });
}
