Struct boa::syntax::ast::node::declaration::ConstDeclList

pub struct ConstDeclList { /* fields omitted */ }

The const statements are block-scoped, much like variables defined using the let keyword.

This declaration creates a constant whose scope can be either global or local to the block in which it is declared. Global constants do not become properties of the window object, unlike var variables.

An initializer for a constant is required. You must specify its value in the same statement in which it's declared. (This makes sense, given that it can't be changed later.)
