I too was recently a beginner and in many ways still am, so I hope the group will excuse my taking this opportunity to mention a few things that might make it easier to help those just starting out with Node-RED.
template nodes. (Unless, of course, the question clearly asks for something more advanced.)
I found the W3schools.com tutorials very helpful, but when a beginner shows obvious ignorance of basic JS or HTML, it may not be helpful just to point to the site and suggest beginning at the beginning. A pointer to a specific topic or section can get someone started in the right direction and show him or her more exactly what needs to be learned. None of us started a new language by learning everything first and coding later.
Finally (and I know I've gone on too long), the fact that NR grows out of a community very familiar with Web development means that it inherits a lot of concepts and tools that may not be known to programmers from a different background. Among the things that were new to me were node.js, npm, git, angular.js, mustache notation, and JSONata. Once the only answer to a beginner's question involves any of those things, I suspect that question no longer belongs in the "Getting Started" category.
