Synchronous method: In this particular approach, we develop a file and create the data to it in a blocking manner, which implies that NodeJS waits for that creation and compose Procedure to accomplish just before transferring on to the next line of code.
Prerequisite - varieties of working units Time sharing working process makes it possible for concurrent execution of applications by way of rapid switching thereby providing Each individual method the same length of time to execute.
serious-time applications are applied when it can be critical that data is processed devoid of lag time. They are often utilised in order to avoid creating a method to halt operating or endanger a user.
