In Node.js, spawn () launches a new process with the available set of commands. This doesn’t generate a new V8 instance only a single copy of the node module is active on the processor. This method can be used when your child process returns a large amount of data to the node.
On the other hand, fork () is a particular case of spawn () which generates a new V8 engines instance. Through this method, multiple workers run on a single node code base for multiple tasks.
