Slack Channel - #truebeginners
A good place to get your feet wet and ask all kinds of questions as to where to start on a subject new to you, or for clarification on things that may be confusing.
Remember: we’re all newbies on one topic or another, so all experience levels are welcome. Chances are you’ll have as much to learn as you will to help others.
This channel is usually for less language-specific questions (eg: learning about classes vs. learning about C#), but feel free to ask here anyway.
