+
+Reuse your objects and functions for maximum speed. This technique will
+make any function run ~10% faster. You call your functions a
+lot, and it adds up quickly in hot code paths.
+
+```
+$ node benchmarks/createNoCodeFunction.js
+Total time 53133
+Total iterations 100000000
+Iteration/s 1882069.5236482036
+
+$ node benchmarks/reuseNoCodeFunction.js
+Total time 50617
+Total iterations 100000000
+Iteration/s 1975620.838848608
+```
+
+The above benchmark uses fibonacci to simulate a real high-cpu load.
+The actual numbers might differ for your use case, but the difference
+should not.
+
+The benchmark was taken using Node v6.10.0.
+
+This library was extracted from
+[fastparallel](http://npm.im/fastparallel).
+
+## Example
+
+```js
+var reusify = require('reusify')
+var fib = require('reusify/benchmarks/fib')
+var instance = reusify(MyObject)
+
+// get an object from the cache,
+// or creates a new one when cache is empty
+var obj = instance.get()
+
+// set the state
+obj.num = 100
+obj.func()
+
+// reset the state.
+// if the state contains any external object
+// do not use delete operator (it is slow)
+// prefer set them to null
+obj.num = 0
+
+// store an object in the cache
+instance.release(obj)
+
+function MyObject () {
+  // you need to define this property
+  // so V8 can compile MyObject into an
+  // hidden class
+  this.next = null
+  this.num = 0
+
+  var that = this
+
+  // this function is never reallocated,
+  // so it can be optimized by V8
+  this.func = function () {
+    if (null) {
+      // do nothing
+    } else {
+      // calculates fibonacci
+      fib(that.num)
+    }
+  }
+}
+```
+
+The above example was intended for synchronous code, let's see async:
+```js
+var reusify = require('reusify')
+var instance = reusify(MyObject)
+
+for (var i = 0; i < 100; i++) {
+  getData(i, console.log)
+}
+
+function getData (value, cb) {
+  var obj = instance.get()
+
+  obj.value = value
+  obj.cb = cb
+  obj.run()
+}
+
+function MyObject () {
+  this.next = null
+  this.value = null
+
+  var that = this
+
+  this.run = function () {
+    asyncOperation(that.value, that.handle)
+  }
+
+  this.handle = function (err, result) {
+    that.cb(err, result)
+    that.value = null
+    that.cb = null
+    instance.release(that)
+  }
+}
+```
+
+Also note how in the above examples, the code, that consumes an istance of `MyObject`,
+reset the state to initial condition, just before storing it in the cache.
+That's needed so that every subsequent request for an instance from the cache,
+could get a clean instance.
+
+## Why
+
+It is faster because V8 doesn't have to collect all the functions you
+create. On a short-lived benchmark, it is as fast as creating the
+nested function, but on a longer time frame it creates less
+pressure on the garbage collector.
+
+## Other examples
+If you want to see some complex example, checkout [middie](https://github.com/fastify/middie) and [steed](https://github.com/mcollina/steed).
