## Singular/Plurals
Like a prefix, variable names can be made singular or plural depending on whether they hold a single value or multiple values.
```js
/* Bad */
const friends = 'Bob';
const friend = ['Bob', 'Tony', 'Tanya'];
/* Good */
const friend = 'Bob';
const friends = ['Bob', 'Tony', 'Tanya'];
```
