JavaScript Classes

Question

I understand basic JavaScript pseudo-classes:

function Foo(bar) {
    this._bar = bar;
}

Foo.prototype.getBar = function() {
    return this._bar;
};

var f         


        

Answer 1

JavaScript classes are introduced in ECMAScript 6 and are syntactical sugar over JavaScript's existing prototype-based inheritance. The class syntax is not introducing a new object-oriented inheritance model to JavaScript. JavaScript classes provide a much simpler and clearer syntax to create objects and deal with inheritance.
