Overview

A JavaScript class is a syntactical superstructure in top of the language's existing prototype-based inheritance, and it does not introduce a new object-oriented inheritance model in JavaScript. A class is a special function, so like in the functions' case, a class syntax has two components: declarations and expressions.

Declaration

Use the class keyword:

class Simplest {
  constructor(content) {
    this.content = content;
  }
}
