It's in fact one of web devs strengths. Web dev cares about UX, so they design it to be accessible. A lot of these libraries and frameworks are about making complex patterns (like lazy loading) easy to do. The hard parts of web dev are still hard (optimizations, caching, architecture, etc), but the entry level is low and there is an abundance of great resources and tooling to help you as you ramp up in complexity.
