The outcome of the callback function has an influence on the exploration of the AST :

• false, the node is not updated and the exploration does not continue further down this branch
• undefined, the node is not updated but the exploration continues and its children will be transformed
• ASTNode, the node is transformed to the new value and the exploration does not continue further down the branch

updateFn : It is possible to specifically use the updated version of a child by using the function passed as second argument. The returned value will be the transformed version of the node.
