@abisalehalliprasan can we upgrade the version of node to something greater than 6, like version 8? Seeing there's an issue with the JS engine not recognizing Object.entries() (https://travis-ci.org/intuit/oauth-jsclient/jobs/593613545#L292).

This shows how it's incompatible with the current version of node: https://node.green/#ES2017-features-Object-static-methods-Object-entries

Yeah, I think it should be fine. I can bump a version up and release, following the sem version.

Looks Good @mcrosby114 👍 🙌
