Tests `fn` as desired + * expect(fn()).to.throw(); // Bad!

Doing so is + * problematic because the `this` context will be lost when the function is + * invoked by `.throw`; there's no way for it to know what `this` is supposed + * to be. There are two ways around this problem. One solution is to wrap the + * method or function call inside of another function. Another solution is to + * use `bind`. + * + * expect(function () { cat.meow(); }).to.throw(); // Function expression + * expect(() => cat.meow()).to.throw(); // ES6 arrow function + * expect(cat.meow.bind(cat)).to.throw(); // Bind + * + * Finally, it's worth mentioning that it's a best practice in JavaScript to + * only throw `Error` and derivatives of `Error` such as `ReferenceError`, + * `TypeError`, and user-defined objects that extend `Error`.
