![]() Just put the code you want to delay in the callback.For example, below is how you can wait 1 second before executing some code. The value returned by the promise is considered as a return value from the await() expression. One way to delay execution of a function in NodeJS is to use the seTimeout() function. Under the async function, we have used the keyword await() to suspend the second console.log() function until the promise has been resolved this takes an average of 4 seconds. The execution will start from the sleep () function. The below code has 3 function func1, func2 and sleep () function. ![]() We will name this function sleep() however, that does not stop you from naming it to any other name that you may find appropriate. Implement a sleep () Function Without Promise, async and await in JavaScript Let’s first see what happens when we don’t use promise, async, and await in our program. ![]() However, using an asynchronous promise-based function, we can use the keyword await() to pause the execution of a piece of code until that promise is fulfilled first. Unlike other programming languages such as C that provide a sleep function, which allows us to sleep a given thread while waiting for another to execute, JavaScript doesn’t have this function. Use the await() Keyword to Pause Execution of Codes in Node.js Function repeatedly executed after every 2 seconds! JavaScript Wait 5 Seconds Function Depending on your preference, you can use either of the two methods to use in the loops.
