I am pretty new here, but I’ve spent quite a bit of time coding in the past month. I don’t profess to be an expert, but here’s a tip to new members:
Go to a secondary source while still using FreeCodeCamp
Even FreeCodeCamp themselves advocates using a secondary source. They routinely link out to the Mozzila Developer Network (MDN). While the MDN is a bit dense for a beginner, there many other resources out there.
Don’t give up! Use FreeCodeCamp as a home base, and be sure to explore on your own. Your learning will greatly increase.
