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;
}
}
