💣 A base class for creating custom JavaScript error classes

Enhances a JavaScript class by adding an is<Class> property to compare types between realms.

The most simple, customizable and easy to use JavaScript standard inheritance library

Adds InstanceOf Expression as Twig Extension

`modern-errors` plugin to execute class-specific logic.

Simple functionality alternative to check data type references such as typeof and instanceof.

Implement prototypical inheritance by replacing the prototype of one constructor with the prototype of another constructor.

Test whether a value has in its prototype chain a specified constructor as a prototype property.

Determine the name of a value's constructor.

The instanceof mechanism cross package/module versions.

Test if an object's prototype chain contains a provided prototype.

Test if a value is a regular expression.
