esmap

Map over esprima nodes conveniently.

Installation

npm install esmap

API

esmap(node, fn(node, key, parent)) -> Node

Maps over the given node's children with the given function. Returns a fresh node.

If a node has a property with an array of children, fn(child, key, node) is called for every child as if they were direct descendants, but the truthy return values are Array#concat'd together. A falsy value is ignored (the node is removed from the array), an array value is concatenated, a non-array value is placed into the array.
