# --description--
You have repetition in the `goTown` and `goStore` functions. Repetition in your code is a sign that you need another function.
In the previous project, you learned how to work with function parameters like this:
```js
function myFunction(param) {
console.log(param);
}
```
Function parameters act as placeholders for values that you pass to the function when you call it.
Create an empty `update` function that takes a parameter called `location`.
# --hints--
You should use the `function` keyword to declare `update`.
```js
assert.match(code, /function\s+update/);
```
Your `update` function should take a parameter called `location`.
```js
assert.match(update.toString(), /update\(\s*location\s*\)/);
```
Your `update` function should be empty.
```js
assert.equal(update.toString(), function update(location) {});
```
