Working with WebRTC

Anybody who worked with WebRTC will agree that there is a huge lack of learning resources and on top of that on every few years, WebRTC standards changes and changes are big sometimes that makes previous resources outdated, creating more gap.

WebRTC is a free, open project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

I have found most of the resources either not clear, not compatible with the current WebRTC library or very incomplete. During my searching for resources, I have found a few as good resources.
