Explore the experimental language Low Level JavaScript (LLJS) in this 30-minute JSConf talk by Michael Bebenita and Shu-yu Guo. Discover how LLJS enables writing memory-efficient and GC pause-free code with predictable performance, making WebGL interfacing more manageable. Learn about linked lists, memory usage, structs, offsets, bit fields, pointers, heap allocation, and implementation details. Gain insights into monomorphic code, manual interfacing, memory leaks, weak references, and interoperability. Understand LLJS's limitations as a specialized tool rather than a general-purpose language.
