estree-parent\n\n\u003e Get parent of an ESTree node\n\n```js\nvar parent = require('estree-parent')\nvar esprima = require('esprima')\n\n// Get source and node somehow:\nvar source = esprima.parse(/* ... */)\nvar node = getNodeSomehow(source)\n\n// Get parent:\nparent(node, source)\n// SwitchStatement { ... }\n```\n\nIt uses a `WeakMap` cache behind the scenes to make repeated use faster\n\n## Installation\n\n```sh\n$ npm install --save estree-parent\n```\n\n## Usage\n\n### `parent(node, source)`\n\nGet parent the parent of a node\n\n - `node` (ESTree `Node`): Node you are getting parent of\n - `source` (ESTree `Node`): Node with children (e.g. `Program`) that contains `node`\n\nReturns `null` if node was not found in the tree\n\n```js\nparent(node, source)\n// FunctionDeclaration { ... }\n\nparent(node)\n// node.parent || null\n```\n\n### `parent.ancestors(node, source)`\n\nGet an array of ancestor nodes from `parent` up to `source`.\n\n - `node` (EStree `Node`): Node you are getting ancestors of\n - `source` (ESTree `Node`): Node with children that contains `node`\n\n```js\nparent.ancestors(node, source)\n// [ ReturnStatement { ... },\n//   SwitchCase { ... },\n//   BlockExpression { ... },\n//   SwitchStatement { ... },\n//   .....\n//   Program { ... } ]\n```\n\n## License\n\nMIT © [Jamen
