Douglas Crockford, author of JavaScript: The Good parts, recently gave a talk called The Better Parts, where he demonstrates how he creates objects in JavaScript nowadays. He doesn't call his approach anything, but I will refer to it as Crockford Classless.
Crockford Classless is completely free of class, new, this, prototype and even Crockfords own invention Object.create.
I think it's really, really sleek, and this is what it looks like:
function dog(spec) {

console.log(1); | |
(_ => console.log(2))(); | |
eval('console.log(3);'); | |
console.log.call(null, 4); | |
console.log.apply(null, [5]); | |
new Function('console.log(6)')(); | |
Reflect.apply(console.log, null, [7]) | |
Reflect.construct(function(){console.log(8)}, []); | |
Function.prototype.apply.call(console.log, null, [9]); | |
Function.prototype.call.call(console.log, null, 10); |
