The document presents a formal semantics for JavaScript, reducing it to a core calculus called λJS, which captures the essential features of the language while addressing its complexities and quirks. The authors demonstrate how JavaScript programs can be desugared into λJS, ensuring that this core model accurately reflects real-world JavaScript behavior through extensive testing against established test suites. Additionally, they explore the implications of their semantics for security by defining a type system that allows for the creation of safe subsets of JavaScript, thereby enhancing security in web applications.
