-# estree-walker
-
-Simple utility for walking an [ESTree](https://github.com/estree/estree)-compliant AST, such as one generated by [acorn](https://github.com/marijnh/acorn).
-
-
-## Installation
-
-```bash
-npm i estree-walker
-```
-
-
-## Usage
-
-```js
-var walk = require( 'estree-walker' ).walk;
-var acorn = require( 'acorn' );
-
-ast = acorn.parse( sourceCode, options ); // https://github.com/acornjs/acorn
-
-walk( ast, {
-  enter: function ( node, parent, prop, index ) {
-    // some code happens
-  },
-  leave: function ( node, parent, prop, index ) {
-  	// some code happens
-  }
-});
-```
-
-Inside the `enter` function, calling `this.skip()` will prevent the node's children being walked, or the `leave` function (which is optional) being called.
-
-Call `this.replace(new_node)` in either `enter` or `leave` to replace the current node with a new one.
-
-Call `this.remove()` in either `enter` or `leave` to remove the current node.
-
-## Why not use estraverse?
-
-The ESTree spec is evolving to accommodate ES6/7. I've had a couple of experiences where [estraverse](https://github.com/estools/estraverse) was unable to handle an AST generated by recent versions of acorn, because it hard-codes visitor keys.
-
-estree-walker, by contrast, simply enumerates a node's properties to find child nodes (and child lists of nodes), and is therefore resistant to spec changes. It's also much smaller. (The performance, if you're wondering, is basically identical.)
-
-None of which should be taken as criticism of estraverse, which has more features and has been battle-tested in many more situations, and for which I'm very grateful.
