When a collection is populated but its contents are never used, then it is surely some kind of mistake. Either refactoring has rendered the
collection moot, or an access is missing.
This rule raises an issue when no methods are called on a collection other than those that add or remove values.
Noncompliant Code Example
function getLength(a, b, c) {
const strings = []; // Noncompliant
strings.push(a);
strings.push(b);
strings.push(c);
return a.length + b.length + c.length;
}
Compliant Solution
function getLength(a, b, c) {
return a.length + b.length + c.length;
}
