+### Esrecurse [![Build Status](https://travis-ci.org/estools/esrecurse.svg?branch=master)](https://travis-ci.org/estools/esrecurse)
+
+Esrecurse ([esrecurse](https://github.com/estools/esrecurse)) is
+[ECMAScript](https://www.ecma-international.org/publications/standards/Ecma-262.htm)
+recursive traversing functionality.
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+esrecurse.visit(ast, {
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+```
+
+We can use `Visitor` instance.
+
+```javascript
+var visitor = new esrecurse.Visitor({
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+
+visitor.visit(ast);
+```
+
+We can inherit `Visitor` instance easily.
+
+```javascript
+class Derived extends esrecurse.Visitor {
+    constructor()
+    {
+        super(null);
+    }
+
+    XXXStatement(node) {
+    }
+}
+```
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    this.visit(node.left);
+    // do something...
+    this.visit(node.right);
+};
+```
+
+And you can invoke default visiting operation inside custom visit operation.
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    // do something...
+    this.visitChildren(node);
+};
+```
+
+The `childVisitorKeys` option does customize the behaviour of `this.visitChildren(node)`.
+We can use user-defined node types.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        // Extending the existing traversing rules.
+        childVisitorKeys: {
+            // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+            TestExpression: ['argument']
+        }
+    }
+);
+```
+
+We can use the `fallback` option as well.
+If the `fallback` option is `"iteration"`, `esrecurse` would visit all enumerable properties of unknown nodes.
+Please note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).
+
+```javascript
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        fallback: 'iteration'
+    }
+);
+```
+
+If the `fallback` option is a function, `esrecurse` calls this function to determine the enumerable properties of unknown nodes.
+Please note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).
+
+```javascript
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        fallback: function (node) {
+            return Object.keys(node).filter(function(key) {
+                return key !== 'argument'
+            });
+        }
+    }
+);
+```
