Tests:
substring + extra obj
function splitCollectionMemberKey(key) { const underscoreIndex = key.indexOf('_'); if (underscoreIndex === -1) { throw new Error(`Invalid ${key} key provided, only collection keys are allowed.`); } return [key.substring(0, underscoreIndex + 1), key.substring(underscoreIndex + 1)]; } IDS.forEach((id) => splitCollectionMemberKey(id));
substring simple
function getCollectionKey(key) { if (!key) { return ''; } const lastUnderscoreIndex = key.lastIndexOf('_'); if (lastUnderscoreIndex === -1) { return key; } return key.substring(0, lastUnderscoreIndex); } IDS.forEach((id) => getCollectionKey(id));
