We had a whole generation of class-heavy inheritance-ridden frameworks and applications. It's bad enough in static languages. In JS, it quickly becomes an unmaintainable pile of spaghetti. Object literals with small doses (read: 1-2 levels at most) can be good. Going further risks multi-level breakage because properties are bound to get added/removed across the codebase over time due to the dynamic nature of JS.
