Direct differences

For readablility some shortcuts are applied:

• named
  • named: 'named'
• [named]
  • [named]: 'named' (non enumerable)
• default
  • default: 'default'
• [default]
  • [default]: 'default' (non enumerable)
• __esModule
  • __esModule: true
• [__esModule]
  • [__esModule]: true (non enumerable)
• [G]
  • [Getter]
• [Module]
  • [Symbol(Symbol.toStringTag)]: 'Module'

import * as x and import() are excluded from these tables as they are too different.
