Rockstar is an esoteric programming language whose syntax is inspired by 1980s hard rock and heavy metal lyrics, making programs read like song lyrics. It uses poetic number literals, where the length of each word in a phrase is parsed as a decimal digit to initialize numeric variables, and pronoun-based variable references, where words like "it" and "they" resolve to the most recently assigned or compared variable at runtime. The language can be compiled to WebAssembly and run inside a web page for in-browser code execution. The language distinguishes itself through a lyric-driven parsing sy
