Function isTruthyAndNotEmpty

Checks whether a value is "truthy" and not an empty object or empty array.

Rules:

• Falsy values (false, 0, '', null, undefined, NaN) return false.
• Empty arrays ([]) return false.
• Empty objects ({}) return false.
• All other values (non-empty arrays, non-empty objects, numbers, strings, booleans, etc.) return true.
