description: >
  When using ROM built-in objects, create a RAM-based global object by creating
  a fresh empty object which inherits from the ROM-based global object.  This
  provides all the standard bindings with a small RAM footprint cost, but still
  allows the global object to be extended and existing bindings overwritten
  (but not deleted).  The downside of this compared to cloning a global object
  is that the inheritance is not fully transparent and the result is less
  compliant.

  Having a writable global object is usually expected; if the global object is
  not writable, it's not possible to e.g. declare functions outside of CommonJS
  modules.
