The first call to my_io_task() starts the timer and leaves it there. Node.js takes less time because of its non-blocking I/O model.

The Python code takes 10 seconds to execute while the Node.js code takes only 5 seconds. Let us assume that a particular I/O task takes 5 seconds to execute, and that we want to perform this I/O twice in our code.īoth look similar, but the time taken to execute are different. Node.js uses callback functions to handle such requests. We know that I/O tasks take much longer than processing tasks. We can also declare our own custom events and make Node.js listen for those events.
Events can be anything from a click to a HTTP request. This means that Node.js waits for certain events to take place. Node.js also uses this super-fast engine to interpret JavaScript files. Google Chrome uses the V8 engine, which is built using C++.
