Optional chaining

Try catch
const testObj = { axaFrInsuranceAgreement: { partyRoleInAgreementGroup: { agreementHolder: { relatedParty: { organization: { establishment: [ { organizationDetailGroup: { organizationInsuranceExperience: [ { claimInPeriodRecords: [ { effectivePeriod: { startDateTime: "string" } } ], } ], }, } ], } } }, }, }, }; const tryGetFnSafely = (fn, defaultVal) => { try { return fn(); } catch (e) { return defaultVal; } }; const testValueOk = tryGetFnSafely(() => testObj.axaFrInsuranceAgreement.partyRoleInAgreementGroup.agreementHolder.relatedParty.organization.establishment[0].organizationDetailGroup.organizationInsuranceExperience[0].claimInPeriodRecords[0].effectivePeriod.startDateTime, null); const testValueErr = tryGetFnSafely(() => testObj.axaFrInsuranceAgreement.partyRoleInAgreementGroup.agreementHolder.relatedParty.organization.establishment[1].organizationDetailGroup.organizationInsuranceExperience[1].claimInPeriodRecords[0].effectivePeriod.startDateTime, null);
