`reusableFunction` should output the string `Hi World` to the console. If `reusableFunction` is called, it should output the string `Hi World` to the console.
```js ```js
assert(hiWorldWasLogged); assert(testConsole());
``` ```
You should call `reusableFunction` after you define it. You should call `reusableFunction` once it is defined.
```js ```js
assert(/^\s*reusableFunction\(\)\s*/m.test(code)); const functionStr = reusableFunction && __helpers.removeWhiteSpace(reusableFunction.toString());
const codeWithoutFunction = __helpers.removeWhiteSpace(code).replace(/reusableFunction\(\)\{/g, '');
assert(/reusableFunction\(\)/.test(codeWithoutFunction));
``` ```
