For personal growth and future possibilities/ooportunities, I think it’s worthwhile to learn coding.
What do jobs pay? Depends on your location, city, skills you have, companies you apply to. I think the big 4 Internet companies pay interns 60K-$80K — INTERNS. Some other companies would probably pay minimum wage for internship positions. Some maybe even $0.
I think around $40K is average entry level programmer position, again, depends on skillsets and experience you have. (in my city at least … if you’re in San Jose, CA probably much higher entry-level salary — but that’s kinda misleading because cost of rent/living is also very very much higher in CA.
Would I be better off and be paid just as much in tech support or even administrative assistant?
At the entry-level position? Probably same level. But you also need to consider future opportunities and career path.
If you already have knowledge of setting up servers/workstations have you considered DevOps? The pay is generally much, much better than the JS frontend coding that FCC mainly teaches. Still coding (so general concepts from FCC are useful, ish), as everything seems to be moving toward using code to automate all the things (Ruby, Python, Bash, Perl scripting mainly, Docker, tools like Terraform, Ansible etc). It’s an absolute pain deploying and running environments for tech, businesses pay an absolute fortune for people who can make them work well.
