Just completed this amazing ebook  by @montalesi. I would recommend anyone who is looking to upgrade their es6, 7 or 8 knowledge to go through the book once. It is short crisp and to the point and serves as a great resource that you can go through in limited time

I have been working as a front-end developer for over 5 years but I am still reading the book by @montalesi because I find it really exhaustive and well written.
