Function transform

transform(node, transformations, o?): Node | Node[]
Recursively execute a callback on this node and all its children. If the callback returns a non-undefined value, it will overwrite the node. This function will not modify the root node of the input tree.
Parameters
- node: Node | Node[]
  Node or array of nodes
- transformations: {} | ((arg0, arg1, arg2, arg3) => any) | ({} | ((arg0, arg1, arg2, arg3) => any))[]
  A map of node types to callbacks, or a single callback that will be called for all node types, or a list of either, which will be applied in order
- Optional o: {
  except: Function | Function[];
  only: Function | Function[];
  }
  - except: Function | Function[]
    Ignore walking nodes of these types
  - only: Function | Function[]
    Only walk nodes of this type
Returns Node | Node[]
The transformation's return value on the root node(s) of the input tree, or the root node(s) if the transformation did not return a value
