ES6 Classes: Syntactic Sugar Mullet – Classy Up Front, Prototype Shenanigans in the Back
Software engineer Timothy discovered that ES6 classes are "syntactic sugar" for prototypes, as explained by Margaret, an expert. The class keyword simplifies code, but underneath, it uses the same prototype chain as before. The "new" keyword performs four steps: creating an object, linking it to the prototype, binding "this" and running the constructor, and returning the object. This understanding, as demonstrated by Timothy's tests, reveals the true nature of JavaScript classes, providing context for developers to write more informed code, as noted by technology writer Aaron Rose.
