no-empty-collection

When a collection is empty it makes no sense to access or iterate it. Doing so anyway is surely an error; either population was accidentally omitted or the developer doesn’t understand the situation.

Noncompliant Code Example

let strings = [];

if (strings.includes('foo')) {} // Noncompliant

for (str of strings) {} // Noncompliant

strings.forEach(str => doSomething(str)); // Noncompliant
