With async/await, you can write asynchronous code that runs in a way that is similar to synchronous code. Using async/awaitĪnother way to create a delay in JavaScript is to use the async/await syntax.

In the example above, the console.log('Before Sleep') statement will be executed immediately, followed by a 3-second delay, after which the console.log('After Sleep') statement will be executed. Here’s an example: console.log('Before Sleep') setTimeout () accepts time in milliseconds, so setTimeout (fn, 1000) tells JavaScript to call fn after 1 second. You can use it to create a delay in your script. To delay a function execution in JavaScript by 1 second, wrap a promise execution inside a function and wrap the Promises resolve () in a setTimeout () as shown below. The setTimeout() function is a built-in JavaScript function that allows you to run a piece of code after a specified amount of time. These calls will block execution of all JavaScript by halting Node. Note that because this is a C++ module, it will need to be built on the system you are going to use it on.
