39. What is the difference between spawn and fork methods in Node.js? The spawn() function is used to create a new process and launch it using the command line. It creates a node module on the processor. Node.js invokes this method when the child processes return data. The following is...
function networkAction(context, method, ...rest) { // rest is an array return method.apply(context, rest); } And if you don’t like calling apply(), you can just spread an array into function arguments: myArguments = ['foo', 'bar', 123]; myFunction(...myArguments); Generators...
