Why is this an issue?

The size of a collection and the length of an array are always greater than or equal to zero. Testing it doesn’t make sense, since the result is always true.

if (someSet.size >= 0) {...} // Noncompliant always true

const result = someArray.length >= 0;  // Noncompliant always true

Similarly testing that it is less than zero will always return false.

if (someMap.size < 0) {...} // Noncompliant always false

Fix the code to properly check for emptiness if it was the intent, or remove the redundant code to keep the current behavior.
