Randell is not wrong, but just as a counter point, a friend of mine from our local meetup group scored a front end dev job before completing his certificate. He was dreadfully underqualified for the position according to the job ad he answered (didn’t know most of the tech they listed as requirements), but he interviewed well and convinced them of his desire to learn.
They gave him the job and started him off building HTML emails (he works for an agency), and after a short while they started training him up in React to get him involved in meatier projects.
So…there’s no harm in applying if there are jobs in your area - you might get them!
You’ll be able to land better jobs if you put more work in ahead of time, and of course different locations will have differing opportunities.
Still, you get 0% of the jobs you don’t apply for, and maybe 0.00001% of those you do when underqualified
