Unlike Java or Python, Javascript does not have a built-in sleep function. So, how might you be able to implement a method with the same functionality as the sleep function? A simple way to create a delay in Javascript is to use the setTimeout method.
To wait properly, you can use anonymous functions: console. log('before'); setTimeout(function(){ console. log('after'); },500);
To delay a function execution in JavaScript by 1 second, wrap a promise execution inside a function and wrap the Promise's resolve() in a setTimeout() as shown below. setTimeout() accepts time in milliseconds, so setTimeout(fn, 1000) tells JavaScript to call fn after 1 second.
You need to re-factor the code into pieces. This doesn't stop execution, it just puts a delay in between the parts.
function partA() {
...
window.setTimeout(partB,1000);
}
function partB() {
...
}
You can't (and shouldn't) block processing with a sleep function. However, you can use setTimeout to kick off a function after a delay:
setTimeout(function(){alert("hi")}, 1000);
Depending on your needs, setInterval might be useful, too.
setTimeout() function it's use to delay a process in JavaScript.
