In contrast to the break statement, continue does not terminate the execution of the loop entirely. JavaScript wait() To make JavaScript wait, use the combination of Promises, async/await, and setTimeout() function through which you can write the wait() function that will work as you would expect it should. ; If the condition evaluates to true, the body of the loop inside the do statement is executed again. This of course is a very bad thing to do in practice, but it’ll help you here to understand that setTimeout delay is not a guaranteed thing, but rather a minimum thing. This means awaits in a for-loop should get executed in series. We'd like a delay in between. The result is what you’d expect. The built-in function setTimeout uses callbacks. Create a promise-based alternative. 'Start' 'Apple: 27' 'Grape: 0' 'Pear: 14' 'End' This behaviour works with most loops (like while and for-of loops)… The continue statement can be used to restart a while, do-while, for, or label statement.. An infinite while loop is started. The delay parameter you pass to these functions is the minimum delay time to execute the callback. Please see the do while loop , i have added that because i have to wait until a timer expires and _stMinExpired is set to true. Essentially in JavaScript there is no way to pause a running loop. I have looked all over and everywhere people are mentioning setTimeout, but that only causes a delayed start of a function.. do statement while (condition); statement A statement that is executed at least once and is re-executed each time the condition evaluates to true. The 1e10 is 1 with 10 zeros in front of it, so the loop is a 10 Billion ticks loop (which basically simulates a busy CPU). Like above example we set a delay to display a message for a spacific times. The HTML5 standard says: “after five nested timers, the interval is forced to be at least 4 milliseconds.”.. Let’s demonstrate what it means with the example below. Then the condition is evaluated. We'll do the same thing as we did in the for-loop example. I just want to slow my for loop so you can visually notice each iteration. This flag is set when a System.threading.timer expires. This returns the number of milliseconds passed since the Epoch time. Await in a forEach loop. Here, The body of the loop is executed at first. ; This process continues until the condition evaluates to false. When you use await, you expect JavaScript to pause execution until the awaited promise gets resolved. Node can do nothing while this loop is ticking. The setTimeout call in it re-schedules itself with zero delay. ; The condition is evaluated once again. ; If the condition evaluates to true, the body of the loop inside the do statement is executed again. But it won't work with loops that require a callback. condition An expression evaluated after each pass through the loop. When you use continue without a label, it terminates the current iteration of the innermost enclosing while, do-while, or for statement and continues execution of the loop with the next iteration. Examples of such loops that require a fallback include forEach, map, filter, and reduce. Just like JavaScript for, for in, do, do while loops. To execute multiple statements within the loop, use a block statement ({ ... }) to group those statements. However, you can only call this custom wait() function from within async functions, and you need to use the await keyword with it. Method 1: Using an infinite loop to keep checking for the elapsed time The time that the sleep function starts is first found using the new Date().getTime() method. The code works fine and does what I want it to do, but the for loop executes so quickly that you don't notice the change in opacity. Each call remembers the real time from the previous one in the times array. Then only i should send next frame. The function delay(ms) should return a promise. That promise should resolve after ms milliseconds, so that we can add .then to it, like this: In the browser, there’s a limitation of how often nested timers can run.
