Low Level JavaScript
summary
Low Level JavaScript is an experimental language that adds C‑style annotations and compiles to JavaScript to let code use a typed‑array heap, emulates a stack, and implement its own allocator. Benchmarks claim about 8x memory reduction versus objects and about 10× speed on linked lists by using compact structs and pointer arithmetic. The prototype ships as a Node CLI, includes a K&R malloc port, requires manual malloc/free, and currently cannot store arbitrary JS objects in the LJS heap.
