You are correct. I work with JS engine implementations most people have never heard of. Performance is different between engine implementations, and so is availability of different ways of solving a task. Using the common browsers' best practice for performance doesn't always work for me. My favorite JS engine is the one implemented in the Evo browser. Among other things, it lacks support for arrays and for loops which makes development a tad interesting. And then we have the iPanel browser built for the Sunniwell set-top-box, in which you have no try/catch. Also, if you use more than five chained if/else, the browser will crash. However, this could be viewed as enforcing general programming best practices :)
