+ * - `object`: This flag contains the target of the assertion. For example, in
+ * the assertion `expect(numKittens).to.equal(7);`, the `object` flag will
+ * contain `numKittens` so that the `equal` assertion can reference it when
+ * needed.
+ *
+ * - `message`: This flag contains an optional custom error message to be
+ * prepended to the error message that's generated by the assertion when it
+ * fails.
+ *
+ * - `ssfi`: This flag stands for "start stack function indicator". It
+ * contains a function reference that serves as the starting point for
+ * removing frames from the stack trace of the error that's created by the
+ * assertion when it fails. The goal is to provide a cleaner stack trace to
+ * end users by removing Chai's internal functions. Note that it only works
+ * in environments that support `Error.captureStackTrace`, and only when
+ * `Chai.config.includeStack` hasn't been set to `false`.
+ *
+ * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
+ * should retain its current value, even as assertions are chained off of
+ * this object. This is usually set to `true` when creating a new assertion
+ * from within another assertion. It's also temporarily set to `true` before

+ *
+ * By default, all of the target's properties are searched when working with

+ * expect({a: 1}).to.include({b: 2}).but.not.own.include({b: 2});
+ *
+ * Note that a target object is always only searched for `val`'s own
+ * enumerable properties.
+ *
+ * `.deep` and `.own` can be combined.
+ *
+ * expect({a: {b: 2}}).to.deep.own.include({a: {b: 2}});
+ *
+ * Add `.nested` earlier in the chain to enable dot- and bracket-notation when

+ *
+ * expect({a: {b: ['x', 'y']}}).to.nested.include({'a.b[1]': 'y'});

+ *
+ * Add `.not` earlier in the chain to negate `.include`.
+ *
+ * expect('foobar').to.not.include('taco');
+ * expect([1, 2, 3]).to.not.include(4);
+ *
+ * However, it's dangerous to negate `.include` when the target is an object.
+ * The problem is that it creates uncertain expectations by asserting that the
+ * target object doesn't have all of `val`'s key/value pairs but may or may
+ * not have some of them. It's often best to identify the exact output that's
+ * expected, and then write an assertion that only accepts that exact output.
+ *
+ * When the target object isn't even expected to have `val`'s keys, it's
+ * often best to assert exactly that.
+ *
+ * expect({c: 3}).to.not.have.any.keys('a', 'b'); // Recommended
+ * expect({c: 3}).to.not.include({a: 1, b: 2}); // Not recommended
+ *
+ * When the target object is expected to have `val`'s keys, it's often best to
+ * assert that each of the properties has its expected value, rather than
+ * asserting that each property doesn't have one of many unexpected values.
+ *
+ * expect({a: 3, b: 4}).to.include({a: 3, b: 4}); // Recommended
+ * expect({a: 3, b: 4}).to.not.include({a: 1, b: 2}); // Not recommended
+ *
+ * `.include` accepts an optional `msg` argument which is a custom error
+ * message to show when the assertion fails. The message can also be given as
+ * the second argument to `expect`.
+ *
+ * expect([1, 2, 3]).to.include(4, 'nooo why fail??');
+ * expect([1, 2, 3], 'nooo why fail??').to.include(4);
+ *
+ * `.include` can also be used as a language chain, causing all `.members` and
+ * `.keys` assertions that follow in the chain to require the target to be a
+ * superset of the expected set, rather than an identical set. Note that
+ * `.members` ignores duplicates in the subset when `.include` is added.
+ *
+ * // Target object's keys are a superset of ['a', 'b'] but not identical
+ * expect({a: 1, b: 2, c: 3}).to.include.all.keys('a', 'b');
+ * expect({a: 1, b: 2, c: 3}).to.not.have.all.keys('a', 'b');

+ * // Target array is a superset of [1, 2] but not identical
+ * expect([1, 2, 3]).to.include.members([1, 2]);

+ *
+ * // Duplicates in the subset are ignored
+ * expect([1, 2, 3]).to.include.members([1, 2, 2, 2]);
+ *
+ * Note that adding `.any` earlier in the chain causes the `.keys` assertion
+ * to ignore `.include`.

+ *
+ * var badFn = function () { throw new TypeError('Illegal salmon!'); };

+ *
+ * When one argument is provided, and it's a regular expression, `.throw`

+ *
+ * var badFn = function () { throw new TypeError('Illegal salmon!'); };
+ *

+ *

+ * Add `.not` earlier in the chain to negate `.throw`.
+ *
+ * var goodFn = function () {};
+ *
+ * expect(goodFn).to.not.throw();
+ *
+ * However, it's dangerous to negate `.throw` when providing any arguments.
+ * The problem is that it creates uncertain expectations by asserting that the
+ * target either doesn't throw an error, or that it throws an error but of a
+ * different type than the given type, or that it throws an error of the given
+ * type but with a message that doesn't include the given string. It's often
+ * best to identify the exact output that's expected, and then write an
+ * assertion that only accepts that exact output.
+ *
+ * When the target isn't expected to throw an error, it's often best to assert
+ * exactly that.
+ *
+ * var goodFn = function () {};
+ *
+ * expect(goodFn).to.not.throw(); // Recommended
+ * expect(goodFn).to.not.throw(ReferenceError, 'x'); // Not recommended
+ *
+ * When the target is expected to throw an error, it's often best to assert
+ * that the error is of its expected type, and has a message that includes an
+ * expected string, rather than asserting that it doesn't have one of many
+ * unexpected types, and doesn't have a message that includes some string.
+ *
+ * var badFn = function () { throw new TypeError('Illegal salmon!'); };
+ *
+ * expect(badFn).to.throw(TypeError, 'salmon'); // Recommended
+ * expect(badFn).to.not.throw(ReferenceError, 'x'); // Not recommended
+ *
+ * `.throw` changes the target of any assertions that follow in the chain to
+ * be the error object that's thrown.
+ *
+ * var err = new TypeError('Illegal salmon!');
+ * err.code = 42;
+ * var badFn = function () { throw err; };
+ *
+ * expect(badFn).to.throw(TypeError).with.property('code', 42);
+ *
+ * `.throw` accepts an optional `msg` argument which is a custom error message
+ * to show when the assertion fails. The message can also be given as the
+ * second argument to `expect`. When not providing two arguments, always use
+ * the second form.
+ *
+ * var goodFn = function () {};
+ *
+ * expect(goodFn).to.throw(TypeError, 'x', 'nooo why fail??');
+ * expect(goodFn, 'nooo why fail??').to.throw();
+ *
+ * Due to limitations in ES5, `.throw` may not always work as expected when
+ * using a transpiler such as Babel or TypeScript. In particular, it may
+ * produce unexpected results when subclassing the built-in `Error` object and
+ * then passing the subclassed constructor to `.throw`. See your transpiler's
+ * docs for details:
+ *
+ * - ([Babel](https://babeljs.io/docs/usage/caveats/#classes))
+ * - ([TypeScript](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work))
+ *
+ * Beware of some common mistakes when using the `throw` assertion. One common
+ * mistake is to accidentally invoke the function yourself instead of letting
+ * the `throw` assertion invoke the function for you. For example, when
+ * testing if a function named `fn` throws, provide `fn` instead of `fn()` as
+ * the target for the assertion.
+ *
+ * expect(fn).to.throw(); // Good! Tests `fn` as desired
+ * expect(fn()).to.throw(); // Bad! Tests result of `fn()`, not `fn`
+ *
+ * If you need to assert that your function `fn` throws when passed certain
+ * arguments, then wrap a call to `fn` inside of another function.
+ *
+ * expect(function () { fn(42); }).to.throw(); // Function expression
+ * expect(() => fn(42)).to.throw(); // ES6 arrow function
+ *
+ * Another common mistake is to provide an object method (or any stand-alone
+ * function that relies on `this`) as the target of the assertion. 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`. No other type of
+ * value will generate a stack trace when initialized. With that said, the
+ * `throw` assertion does technically support any type of value being thrown,
+ * not just `Error` and its derivatives.
+ *
