### objectToQueryString
Returns a query string generated from the key-value pairs of the given object.
Use `Array.prototype.reduce()` on `Object.entries(queryParameters)` to create the query string.
Determine the `symbol` to be either `?` or `&` based on the `index` and concatenate `val` to `queryString` only if it's a string.
Return the `queryString` or an empty string when the `queryParameters` are falsy.
```js
const objectToQueryString = queryParameters => {
return queryParameters
? Object.entries(queryParameters).reduce((queryString, [key, val], index) => {
const symbol = index === 0 ? '?' : '&';
queryString += (typeof val === 'string') ? `${symbol}${key}=${val}` : '';
return queryString;
}, '')
: '';
};
```
<details>
<summary>Examples</summary>
```js
objectToQueryString({page: '1', size: '2kg', key: undefined}); // '?page=1&size=2kg'
```

### parseCookie
