📄 Description

Port of https://github.com/langchain-ai/langgraph/pull/2352, allows both [key: string, action: function][] and { [key: string]: function }

Objects might be a little bit strange, but I think in current JS engine implementation of Object.entries is reasonably defined for us to do this.

Within each component of the prototype chain, all non-negative integer keys (those that can be array indices) will be traversed first in ascending order by value, then other string keys in ascending chronological order of property creation.
