== Why is this an issue?

If a class method doesn't access properties of that class (i.e. it doesn't use ``++this++``), it should be made ``++static++``.

=== Noncompliant code example

[source,javascript]
----
class Foo {
  constructor() {
    this.i = 1;
  }

  bar() {
    window.focus();
  }
}
----

=== Compliant solution

[source,javascript]
----
class Foo {
  constructor() {
    this.i = 1;
  }

  static bar() {
    window.focus();
  }
}
----

=== Exceptions

The constructor is exempt of this rule.
