Node.js multithreading allows for improved performance and reduced bottlenecks in applications by running code in parallel. Worker threads are the equivalent of web workers in Node.js and can be used to offload processing to separate threads. SharedArrayBuffer objects can be used to share data between threads, and child processes and clustering can also be used for parallel processing.
