summary:
# Invariant In program semantics, an **invariant** of a piece of code is a condition that is provably true throughout the execution of that code. Defining invariants helps to reason about the code's correctness and behavior. For example, in the following code: We can prove that `count` is a non-negative integer from the beginning to the end. This means that anywhere in the code, we can pass `count` to a function that expects a non-negative integer, and the function will work correctly. Invariants can be established in two ways: by the nature of the program, or by explicit assertions (runtime checks). For example, the code above does not perform any checks, but by virtue of `count` being an incrementing integer starting from `0`, we can guarantee its range. If we are receiving input from an external source, we can use checks to establish invariants at the boundary: Invariants are particularly useful in complex systems that cannot afford to perform exhaustive checks at every step. We establish invariants at the system boundary, and then any following code can assume those properties without checking them again. In general, anything that can be assumed to be true is an invariant. For example, a

summary:
# JSON type representation [JSON](https://developer.mozilla.org/en-US/docs/Glossary/JSON) is a convenient and widely used format for serializing objects, arrays, numbers, strings, booleans, and null. [JSON does not support all data types allowed by JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON#javascript_and_json_differences), which means that JavaScript objects that use these incompatible types cannot be directly serialized to JSON. The _JSON type representation_ of a JSON-incompatible object is an equivalent JavaScript object with properties encoded such that the information _can_ be serialized to JSON. This typically has the same properties as the original object for compatible data types, while incompatible properties are converted/serialized to compatible types. For example, buffer properties in the original object might be [base64url](https://developer.mozilla.org/en-US/docs/Glossary/Base64)-encoded to strings in the JSON-type representation. An object that cannot automatically be serialized to JSON using the [`JSON.stringify()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) method can define an instance method named `toJSON()` that returns the _JSON-type representation_ of the original object. [`JSON.stringify()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) will then use `toJSON()` to get the object to stringify, instead of the original object. [`PublicKeyCredential.toJSON()`](https://developer.mozilla.org/en-US/docs/Web/API/PublicKeyCredential/toJSON) and [`Performance.toJSON()`](https://developer.mozilla.org/en-US/docs/Web/API/Performance/toJSON) are examples of this approach. A JSON string serialized in this way can be deserialized back to the _JSON-type representation_ object using [`JSON.parse()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse). It is common to provide a converter method, such as [`PublicKeyCredential.parseCreationOptionsFromJSON()`](https://developer.mozilla.org/en-US/docs/Web/API/PublicKeyCredential/parseCreationOptionsFromJSON_static "PublicKeyCredential.parseCreationOptionsFromJSON\(\)"), to convert the _JSON-type representation_ back
