In this code, Print first is displayed first and then the function execution is paused for 2 seconds before the next line of code is executed.

In programming languages like C, Ruby, or Python pausing or delaying function execution is pretty straightforward as you would only need to call the sleep function.įor instance, consider the following Python function: import time However, there are different methods you can use to implement its functionality. Now, we don’t have a headache if a couple of timers are required to be run. The Node.Js sleep function does not exist. With this new syntax, waiting for a timer looks almost the same as traditional sleep call in a synchronous language. Similarly, PHP has sleep (2), and Python has time.sleep (2) to make the program stops for 2 seconds.

For example, in Java, you can use the Thread.sleep (2 1000) to halt the current thread execution for 2 seconds. Just put the code you want to delay in the callback. Many programming languages provide a sleep () function that pauses the execution of the code for a certain amount of time. How can we sleep or delay using Node.Js Javascript? One way to delay execution of a function in NodeJS is to use the seTimeout () function.
