2: Ruby and JavaScript, with "proficiency" means that I have good knowledge of the language APIs, general best practices, and sufficient mastery of the vanilla language (eg outside of Rails or React) to accomplish complex functionality using the native tools (eg I know how to metaprogram and ruby as well as not to metaprogram in ruby, and how context and `bind` work in JS). I also know some PHP, Python, etc, but not to a capacity where I can just sit down and write a program without consulting some guides/docs, and no experience with the popular frameworks.
