Option	Description	Default Value
defaultValue	If the resolved value is undefined, the defaultValue is returned in its place.	undefined
excludeNull	if the resolved value is null, the defaultValue is returned in its place.	false

const data = {its: {really: {really: {really: {nested : undefined}}}}, nested: {value: null}};
const result = get(data, data => data.its.really.really.really.nested, 'defaultValue');

• has(object, getFn) - Checks if path is a direct property of object.

const data = {its: {really: {really: {}}, b: {}};
const result = has(data, data => data.its.really.really.really.nested);

expect(result).toEqual(false);
