One could imagine a version of Node built on a hypothetical JavaScript-sans-Arrays. In such a world, packages would have to invent array types for themselves. The lingua franca array would be a number-keyed object, and packages would have to downcast their interpretation of arrays down to number-keyed objects at their thresholds. If a package missed doing this, their definition of an array would leak into calling packages. What if contemporary arrays were introduced into this ecosystem? At some level, they're still just sugar for objects-with-numeric-keys; but they'd have the potential to give packages a global interchange datatype for arrays. At the very least users would start passing them between packages. They'd expect native Arrays to work. Eventually there would be pressure on core to adopt the native Array. Would we do it?

The result of the above hypothetical is not that arrays replace objects, it's that native Arrays replace ad-hoc definitions of arrays. Native Arrays standardize the interchange form

For Latour all reality is political,
not because human power inexorably shapes the truth, but because truth
and reality are assembled through chains of actors in the same way that
bills go through Congress: slightly transformed and translated at each step,
and failing as often as they succeed. All reality is political, but not all poli-
tics is human.
referring to the ‘cosmopolitics’ of his friend Isabelle Stengers,
Latour speaks of a redefined political order that ‘brings together stars, pri-
