+
+> Ensure a function is only called once
+
+When called multiple times it will return the return value from the first call.
+
+*Unlike the module [once](https://github.com/isaacs/once), this one isn't naughty extending `Function.prototype`.*
+
+
+## Install
+
+```
+$ npm install --save onetime
+```
+
+
+## Usage
+
+```js
+let i = 0;
+
+const foo = onetime(() => i++);
+
+foo(); //=> 0
+foo(); //=> 0
+foo(); //=> 0
+```
+
+```js
+const foo = onetime(() => {}, {throw: true});
+
+foo();
+
+foo();
+//=> Error: Function `foo` can only be called once
+```
+
+
