WebAssembly SIMD will expose hardware SIMD instructions to WebAssembly applications in a platform-independent way. The SIMD proposal introduces a new 128-bit value type that can be used to represent different types of packed data, and several vector operations that operate on packed data. SIMD can boost performance by exploiting data level parallelism and is also useful when compiling native code to WebAssembly
