18. Downloading — it is more compact, so can be faster to download Parsing — decoding WebAssembly is faster than parsing JavaScript Compiling & optimizing — it takes less time to compile and optimize because more optimizations have been done before the file is pushed to the server, and the code does need to be compiled multiple times for dynamic types Re-optimizing — code doesn’t need to be re-optimized because there’s enough information for the compiler to get it right on the first try Execution — execution can be faster because WebAssembly instructions are optimized for how the machine thinks Garbage Collection — garbage collection is not directly supported by WebAssembly currently, so there is no time spent on GC
