There are two gotchas that strict equality has, `NaN` and zeroes. Adding negative zero further illustrates that strict equality is not enough and we need [Object.is](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is#Description). A further pull request can add `Object.is` to the legend.
