In this new era of agentic web development, developers expect their coding agents to be experts at building for the web. And while the latest frontier coding models are quite capable and can usually produce something that works, if you ask a web development expert to review the AI-generated code, they can almost always find ways to make the code faster, more accessible, or more secure.
