• node._blockHoist: node._blockHoist != null triggers the block-hoist transformer. Value should be true or an integer in the range 0..3. true is equivalent to 2. The value indicates whether the node should be hoisted and to what degree. See the source code for more detailed information.
• node.shadow: A truthy value on a function node triggers the shadow-functions transformer, which transforms the node so that it references (or inherits) arguments and the this context from the parent scope. It is invoked for arrow functions or when we want to create a function that is "invisible".
  • true is equivalent to { arguments: true, this: true}
  • false is an noop.
• node._paths: Stores a representation of a node's position in the tree and relationship to other nodes.
