Lets use this thread to share ideas on how to get started with PCF for the uninitiated.
So, I'm techie, but have never delved into a specific programming language. I mostly just learn enough to be dangerous/complete the task at hand then move on. Power Apps and Power Automate (Flow) have been the exception to this behaviour. These tools roped me in ~2 years ago and I've been all-in since.
Now I stand at the door of "real" programming. I stand here staring down the PowerApps Component Framework (PCF) like a cowboy in the corral... hand quavering just above my keyboard...ready to "DRAW!" Bang! Bang! Bang!
Except... I don't know where to start!
Venturing into react very early will overwhelm beginners as there is lot of distractions along the way. Keep it simple for now till you have a solid understanding of how things are hooked up. The key thing is to use the Dev Tools to understand what is happening under to hood. This is now much easier with the harness, as you don't need to deploy the component to play with it.
