The JS-BigInt-Integration feature makes it easy to pass 64-bit integers between JavaScript and WebAssembly. This post explains what that means and why it’s useful, which includes making things simpler for developers, letting code run more quickly, and also speeding up build times.
SIMD stands for Single Instruction, Multiple Data. SIMD instructions are a special class of instructions that exploit data parallelism in applications by simultaneously performing the same operation on multiple data elements. Compute intensive applications like audio/video codecs, image processors, are all examples of applications that take advantage of SIMD instructions to accelerate performance. Most modern architectures support some variants of SIMD instructions.
