With hooks, I've literally seen almost completely novice programmers (e.g., people who’d hacked out some powershell while working desktop support previously) pick up React and be productive in a month or so, while also learning JS and Python and SQL and backend development from scratch in parallel; if backend “engineers” can't do it in half a week or so, they’re hacks.
