+# Function Once
+
+Wraps a function so that it's only ever executed once.
+
+Note: `this` is always set to `undefined` and only functions that don't accept any arguments are supported, as using those with a function that's only ever executed once is practically just a footgun. If you need different `this` or different arguments you should probably use memoization instead.
+
+## Install
+
+```sh
+npm install --save function-once
+```
+
+## Usage
+
+```ts
+import once from 'function-once';
+
+const rand = once (() => Math.random ());
+
+rand (); // => 0.3344627371267874
+rand (); // => 0.3344627371267874
+```
