So, in order to rewrite your function we have to take this into account. The fundamental difference is that sleep (as used in many other languages) is synchronous, while setTimeout (and many other JavaScript-concepts, like AJAX for example) are asynchronous. To transform seconds into milliseconds you will need to multiply your seconds by 1000. To complete this task, first of all, you will need to transform seconds into milliseconds. I dont fully understand what you're asking, but I'm going to answer this part: Luckily for us, JavaScript provides a few ways for a developer to wait X seconds before executing the next line of the code. while (curr - start < time) is tricky, but it won't work (just stops my browser and then throw all console logs at once). + fib(n)) and sleep after every "+"? Nah, sleep would be muuuuuch easier.īut still I can't get working example of implementing it. If you know how to get the same result using setTimeout - tell me ) fibanacci is pretty easy task, because there aren't more than 2 recursions, but how about n-recursions (like fib(1) + fib(2) +. wait 1 second before announcing the result wait 1 second before computing for lower n please, don't tell me about setTimeout method because - yes, everything is possible with that but not so easy as using sleep() method.Ĭonsole.log("Computing Fibonacci for " + n + ".") With async/await, you can write asynchronous code that runs in a way that is similar to synchronous code.Yes, I know - that question has thousands of answers. 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') You can use it to create a delay in your script. The setTimeout() function is a built-in JavaScript function that allows you to run a piece of code after a specified amount of time. Starting at only $16.50 per month! DOWNLOAD NOW This returns the number of milliseconds passed since the Epoch time. The time that the sleep function starts is first found using the new Date ().getTime () method. Since neither the first nor the second function's timers have completed, the third function is called and completes its execution first. Method 1: Using an infinite loop to keep checking for the elapsed time.
