"The truth is if you think you know NodeJS well, read the docs." This is what I tell my friends and mentees. Packages have abstracted most things for us, of course, that’s the showers of love and gifts from the awesome community. But definitely, there will be a time when a root knowledge of NodeJS will come in handy. Perhaps you could have quickly suppressed that client’s issue and save your company’s money and client, only if you have that particular NodeJS root knowledge. So now more than ever is the time to look into them. In this talk, we will together explore the gems I found after digging into NodeJS docs and what cases or scenarios they can be helpful for. Glad I did and glad and motivated you will also be when you hear about them.
