Description

Because it is necessary to list all hoisted declarations when evaluating a js tree (variables and first level functions), I think Program and Function declarations should store the list of statements that are visible at their levels.

In esprima.net I created a new context variable to store the declarations as parsed, and copy them to the parsed scope object (program and function declaration)

Research direction

Start by tracing how Program and Function declarations are parsed and how their scope objects are created. Review the existing declaration-handling context and compare it with the referenced esprima.net approach. Done means both scope types retain the statements visible at their level, with tests demonstrating hoisted variables and first-level functions.
