Mar 10, 2024 · Classes are a template for creating objects. They encapsulate data with code to work on that data. Classes in JS are built on prototypes but also have some syntax and semantics that are unique to classes. For more examples and explanations, see the Using classes guide.
In JavaScript, classes are mainly an abstraction over the existing prototypical inheritance mechanism — all patterns are convertible to prototype-based inheritance. Classes themselves are normal JavaScript values as well, and have their own prototype chains.
