Prevents the modification of existing property attributes and values, and prevents the addition of new properties.
Object on which to lock the attributes.
Gets the own property descriptor of the specified object. An own property descriptor is one that is defined directly on the object and is not inherited from the object's prototype.
Object that contains the property.
Name of the property.
Returns an object containing all own property descriptors of an object
Object that contains the properties and methods. This can be an object that you created or an existing Document Object Model (DOM) object.
Returns the names of the own properties of an object. The own properties of an object are those that are defined directly on that object, and are not inherited from the object's prototype. The properties of an object include both fields (objects) and functions.
Object that contains the own properties.
Returns an array of all symbol properties found directly on object o.
Object to retrieve the symbols from.
Returns the prototype of an object.
The object that references the prototype.
Returns true if the values are the same value, false otherwise.
The first value.
The second value.
Returns a value that indicates whether new properties can be added to an object.
Object to test.
Returns true if existing property attributes and values cannot be modified in an object, and new properties cannot be added to the object.
Object to test.
Returns true if existing property attributes cannot be modified in an object and new properties cannot be added to the object.
Object to test.
Returns the names of the enumerable string properties and methods of an object.
Object that contains the properties and methods. This can be an object that you created or an existing Document Object Model (DOM) object.
Returns the names of the enumerable string properties and methods of an object.
Object that contains the properties and methods. This can be an object that you created or an existing Document Object Model (DOM) object.
Prevents the addition of new properties to an object.
Object to make non-extensible.

Object on which to lock the attributes.
Sets the prototype of a specified object o to object proto or null. Returns the object o.
The object to change its prototype.
The value of the new prototype or null.
Returns an array of values of the enumerable properties of an object
Object that contains the properties and methods. This can be an object that you created or an existing Document Object Model (DOM) object.
Returns an array of values of the enumerable properties of an object
Object that contains the properties and methods. This can be an object that you created or an existing Document Object Model (DOM) object.
JS analogue of Polar's Dictionary type.
Polar dictionaries allow field access via the dot operator, which mirrors the way JS objects behave. However, if we translate Polar dictionaries into JS objects, we lose the ability to distinguish between dictionaries and instances, since all JS instances are objects. By subclassing
Object, we can useinstanceofto determine if a JS value should be serialized as a Polar dictionary or external instance.
