+# onetime
+
+> 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 and extending `Function.prototype`.*
+
+## Install
+
+```
+$ npm install onetime
+```
+
+## Usage
+
+```js
+import onetime from 'onetime';
+
+let index = 0;
+
+const foo = onetime(() => ++index);
+
+foo(); //=> 1
+foo(); //=> 1
+foo(); //=> 1
+
+onetime.callCount(foo); //=> 3
+```
+
+```js
+import onetime from 'onetime';
+
+const foo = onetime(() => {}, {throw: true});
+
+foo();
+
+foo();
+//=> Error: Function `foo` can only be called once
+```
+
