Called on an object instance, returns a string representation of the object. Accepts an optional locale as argument.

Returns the `[object Object]` string unless overridden. Objects can then return a different string representation depending on the locale.

```js
const person = { name: 'Fred' }
person.toLocaleString() //[object Object]
```
