concurrentTasksPerWorker: (number) Specifies how many tasks can share a single Worker thread simultaneously. The default is 1. This generally only makes sense to specify if there is some kind of asynchronous component to the task. Keep in mind that Worker threads are generally not built for ha...

The more complex the task, the worse this can get. By nesting callbacks in such a way, we easily end up with error-prone, hard to read, and hard to maintain code. One workaround is to declare these tasks as small functions, and then link them up. Although, one of the (arguably) ...

It enables Node.js to handle multiple concurrent requests efficiently without blocking the main thread. What is Node.js used for? Node.js is primarily used for building server-side applications and command-line tools. It also plays a role in front-end development through build tools and ...
The concurrent “processes” are the tworesponse()calls that will be made to handle the Ajax responses. They can happen in either-first order. Let’s assume the expected behavior is thatres[0]has the results of the"http://some.url.1"call, andres[1]has the results of the"http://some...
