Operator Lookup Makes JavaScript Operators Fun to Explore

Josh Comeau has launched Operator Lookup, a slick new site that breaks down how JavaScript operators work. Each operator comes with handy code examples that show what it does in practice.

The standout UI detail is the tag set under the search bar—you can click any operator to get details, and hovering over a tag triggers a tiny, satisfying click sound. It's a rare treat to get real audio feedback in a web interface.
