This extension allows you to view information about class member overrides and implementations in the form of CodeLens annotations for JavaScript and TypeScript.
When a method or field is overriden, a clickable @Override <name> text appears that opens a peek window for the method or field that is overriden, while stating the name of the class or interface of the original implementation.
A lens with the text @Implement <name> shows above a method or property that implements an abstract method or property, or an interface.
Showcase
Basic: Below is an example of the basic functionality of this extension, name and constructor are being overridden from Animal which is reflected with the @Override Animal annotation. speak(), on the other hand, is being implemented which is why the annotation shows @Implement Animal. Theme: Theme³
Peek: Clicking an annotation opens a peek window and selects the relevant method or property in this peek window. Theme: Theme³
Implementing multiple interfaces: If a class implements multiple interfaces, the annotations are shown for all these interfaces. Theme: Theme³
Deep Annotations: To find out whether a method or property is being overridden, it checks the entire tree of superclasses, so it even shows indirect overrides (@Implement Animal is shown at line 22, since Fish extends Animal which has a speak() method). Theme: Theme³
