You can really tell when web developers don&#x27;t actually use the website they&#x27;re building (especially contractors). Same for applications and for overly complex software where developers only use few features themselves (hence web browser bugs).<p>Only very talented or disciplined people manage to write flawless code without stumbling over their own bugs first. A good, opinionated, statically typed language helps, IMHO (scripting languages are one of the reasons for crappy web pages).
