If a function does not return anything, it makes no sense to use its output. Specifically, passing it to another function, or assigning its
"result" to a variable is probably a bug because such functions return undefined, which is probably not what was intended.
Noncompliant Code Example
function foo() {
  console.log("Hello, World!");
}

a = foo();

Compliant Solution
function foo() {
  console.log("Hello, World!");
}

foo();
