To me, the important thing with class literals is to use naming consistently.
If the class is named Point and you want to add properties to it, it seems odd
to use an operator to add those properties to (what looks like) a method called
"constructor". Under the hood, it makes sense. Superficially (with a sugared
eye), it’s confusing.

I kind of like the idea of parameterized object literals. But then I have no
idea where class properties would go:
class Point(x,y) {
x: x,
y: y,
prototype {
manhattanDistance() {
return Math.abs(this.x) + Math.abs(this.y);
}
}
}
