Actually I'm a mechanical engineer, but also a self-made "fullstack developer" with decent skills in HTML, CSS and JS, and messing around with PHP and PostgreSQL at the back-end. (In the past I've worked with ((Auto-Lisp( in various projects)))), but C# has replaced the old good Lisp for years ago. Web page developing is just for fun, and Auto-Lisp and C# have been a great help, when bringing home the bacon.
If you have a question:
- Define "It doesn't work" in the question, don't write the phrase literally
- Reading the documentation is always useful
NaNis not an error, it's a value
- Don't minify your developement code
Also: When responding to a comment or an answer, please think faster than you can write!
