+
+> Snapdragon utility for creating a new AST node in custom code, such as plugins.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save snapdragon-node
+```
+
+## Usage
+
+With [snapdragon](https://github.com/jonschlinkert/snapdragon) v0.9.0 and higher you can use `this.node()` to create a new `Node`, whenever it makes sense.
+
+```js
+var Node = require('snapdragon-node');
+var Snapdragon = require('snapdragon');
+var snapdragon = new Snapdragon();
+
+// example usage inside a parser visitor function
+snapdragon.parser.set('foo', function() {
+  // get the current "start" position
+  var pos = this.position();
+
+  // returns the match if regex matches the substring 
+  // at the current position on `parser.input`
+  var match = this.match(/foo/);
+  if (match) {
+    // call "pos" on the node, to set the start and end 
+    // positions, and return the node to push it onto the AST
+    // (snapdragon will push the node onto the correct
+    // nodes array, based on the stack)
+    return pos(new Node({type: 'bar', val: match[0]}));
+  }
+});
+```
+
+## API
+
+### [Node](index.js#L22)
+
+Create a new AST `Node` with the given `val` and `type`.
+
+**Params**
+
+* `val` **{String|Object}**: Pass a matched substring, or an object to merge onto the node.
+* `type` **{String}**: The node type to use when `val` is a string.
+* `returns` **{Object}**: node instance
+
+**Example**
+
+```js
+var node = new Node('*', 'Star');
+var node = new Node({type: 'star', val: '*'});
+```
+
+### [.isNode](index.js#L61)
+
+Returns true if the given value is a node.
+
+**Params**
+
+* `node` **{Object}**
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+var Node = require('snapdragon-node');
+var node = new Node({type: 'foo'});
+console.log(Node.isNode(node)); //=> true
+console.log(Node.isNode({})); //=> false
+```
+
+### [.define](index.js#L80)
+
+Define a non-enumberable property on the node instance. Useful for adding properties that shouldn't be extended or visible during debugging.
+
+**Params**
+
+* `name` **{String}**
+* `val` **{any}**
+* `returns` **{Object}**: returns the node instance
+

+Returns true if `node.val` is an empty string, or `node.nodes` does not contain any non-empty text nodes.
+
+**Params**
+
+* `fn` **{Function}**: (optional) Filter function that is called on `node` and/or child nodes. `isEmpty` will return false immediately when the filter function returns false on any nodes.
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+var node = new Node({type: 'text'});
+node.isEmpty(); //=> true
+node.val = 'foo';
+node.isEmpty(); //=> false
+```
+
+### [.push](index.js#L118)

+var bar = new Node({type: 'bar'});
+foo.push(bar);
+```
+
+### [.unshift](index.js#L140)
+
+Given node `foo` and node `bar`, unshift node `bar` onto `foo.nodes`, and set `foo` as `bar.parent`.
+
+**Params**
+
+* `node` **{Object}**
+* `returns` **{Number}**: Returns the length of `node.nodes`
+
+**Example**
+
+```js
+var foo = new Node({type: 'foo'});
+var bar = new Node({type: 'bar'});
+foo.unshift(bar);

+
+**Example**
+
+```js
+var node = new Node({type: 'foo'});
+node.push(new Node({type: 'a'}));
+node.push(new Node({type: 'b'}));
+node.push(new Node({type: 'c'}));
+node.push(new Node({type: 'd'}));
+console.log(node.nodes.length);
+//=> 4
+node.pop();
+console.log(node.nodes.length);
+//=> 3
+```
+
+### [.shift](index.js#L190)

+```js
+var node = new Node({type: 'foo'});
+node.push(new Node({type: 'a'}));
+node.push(new Node({type: 'b'}));
+node.push(new Node({type: 'c'}));
+node.push(new Node({type: 'd'}));

+* `node` **{Object}**
+* `returns` **{Object}**: Returns the removed node.
+
+**Example**
+
+```js
+node.remove(childNode);
+```
+
+### [.find](index.js#L231)

+
+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-descriptor
+```
+
+## Usage
+
+```js
+var isDescriptor = require('is-descriptor');
+
+isDescriptor({value: 'foo'})
+//=> true
+isDescriptor({get: function(){}, set: function(){}})
+//=> true
+isDescriptor({get: 'foo', set: function(){}})
+//=> false
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+var obj = {};
+obj.foo = 'abc';
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+isDescriptor(obj, 'foo');
+//=> true
+isDescriptor(obj, 'bar');
+//=> true
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+isDescriptor('a');
+//=> false
+isDescriptor(null);
+//=> false
+isDescriptor([]);
+//=> false
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({value: 'foo'});
+//=> true
+isDescriptor({value: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({value: 'foo', get: noop});
+//=> false
+isDescriptor({get: noop, value: noop});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({value: 'foo', enumerable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', configurable: 'foo'});
+//=> false
+isDescriptor({value: 'foo', writable: 'foo'});
+//=> false
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+isDescriptor({get: noop, set: noop});
+//=> true
+isDescriptor({get: noop});
+//=> true
+isDescriptor({set: noop});
+//=> true
+```
+
+`false` when the object has invalid properties
+
+```js
+isDescriptor({get: noop, set: noop, bar: 'baz'});
+//=> false
+isDescriptor({get: noop, writable: true});
+//=> false
+isDescriptor({get: noop, value: true});
+//=> false
+```
+
+`false` when an accessor is not a function
+
+```js
+isDescriptor({get: noop, set: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: noop});
+//=> false
+isDescriptor({get: 'foo', bar: 'baz'});
+//=> false
+isDescriptor({get: 'foo', set: 'baz'});
+//=> false
+```
+
+`false` when a value is not the correct type
+
+```js
+isDescriptor({get: noop, set: noop, enumerable: 'foo'});
+//=> false
+isDescriptor({set: noop, configurable: 'foo'});
+//=> false
+isDescriptor({get: noop, configurable: 'foo'});
+//=> false

+
+## Optimizations
+
+In 7 out of 8 cases, this library is 2x-10x faster than other top libraries included in the benchmarks. There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library:
+
+1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot.
+2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it.
+3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'`
+4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written.
+
+## Better type checking
+
+kind-of is more correct than other type checking libs I've looked at. For example, here are some differing results from other popular libs:
+
+### [typeof](https://github.com/CodingFu/typeof) lib
+
+Incorrectly tests instances of custom constructors (pretty common):
+
+```js
+var typeOf = require('typeof');
+function Test() {}
+console.log(typeOf(new Test()));
+//=> 'test'
+```
+
+Returns `object` instead of `arguments`:
+
+```js
+function foo() {
+  console.log(typeOf(arguments)) //=> 'object'
+}
+foo();
+```
+
+### [type-of](https://github.com/ForbesLindesay/type-of) lib
+
+Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`:
+
+```js
+function * foo() {}
+console.log(typeOf(foo));
+//=> 'object'
+console.log(typeOf(new Buffer('')));
+//=> 'object'
+console.log(typeOf(new Map()));
+//=> 'object'
+console.log(typeOf(new Set()));
+//=> 'object'
+console.log(typeOf(new WeakMap()));
+//=> 'object'
+console.log(typeOf(new WeakSet()));
+//=> 'object'
+```
