In JavaScript, the Web Workers API is used to create threads.
Worker threads run in the background, allowing the main program to continue executing without interruption. By enabling concurrent execution, worker threads can help save time by running different parts of a program simultaneously.
Shared memory is a feature that enables threads (different parts of a program) to access and modify the same data in shared memory.
Instead of transferring data between threads, you can pass a SharedArrayBuffer object that references the memory location where the data is stored.
A SharedArrayBuffer object represents a fixed-length raw binary data buffer, similar to the ArrayBuffer object, but designed for shared memory access across threads.
