_super and _super_ keywords in javascript?

Question

I am new to JS and in the process of reading about prototypes, so I came across various examples using keywords such as _superor_super_

Are these native javascript constructors, for example, a prototype or some add-ons that implement third-party libraries to help with inheritance?

Answer 1

These words are third-party additions. There is no reserved word _superor in JavaScript _super_.
