An instance is allocated for a large share of walked expressions, so the boolean facts live in one packed flags slot and the scalar/identifier fields in five slots shared by type, with accessors keeping every public field readable. This shrinks instances from 224 to 144 bytes on V8.

BasicEvaluatedExpression[]Served lazily from the attached expression when not set explicitly:
evaluateExpression's plain results share the expression's range, and
most evaluations never read it, so the node's range array is only
materialized on demand.
