Originally JavaScript didn't support ``++class++``es, and class-like behavior had to be kludged using things like ``++prototype++`` assignments for "class" functions. Fortunately, ECMAScript 2015 added classes, so any lingering ``++prototype++`` uses should be converted to true ``++class++``es. The new syntax is more expressive and clearer, especially to those with experience in other languages.

Specifically, with ES2015, you should simply declare a ``++class++`` and define its methods inside the class declaration.

== Noncompliant Code Example

function MyNonClass(initializerArgs = []) {
|
|
this._values = [...initializerArgs];
|
|
}
|
|
|
|
MyNonClass.prototype.doSomething = function () { // Noncompliant
|
|
// ...
|
|
}
