Running in lower version node will error

[zhongzhi107]

node -v
v 4.2.1

The reason is that the default function defaults are not supported in the lower version

The error message is as follows：

`
/node_modules/object-assign-deep/objectAssignDeep.js:77

function executeDeepMerge (target, _objects = [], _options = {}) {

                                        ^

SyntaxError: Unexpected token =

Hi @zhongzhi107, yes we only support Node 6 and newer. You can check the supported versions in the "engines" property of package.json.
