First road bike: mech disc brakes vs dual pivot sidepull brakes? What you can do is wrap the entire loop within an async function and await a Promise that contains the setTimeout as shown: Please take some time to get a good understanding of asynchronous programming. for loop; while loop; do…while loop; How to use Loop? Works in Node 8. for common use "forget normal loops" and use this combination of "setInterval" includes "setTimeOut"s: like this (from my real tasks). You may want to use something like this instead: You could also neaten it up, by using a self invoking function, passing the number of iterations as an argument: Since ES7 theres a better way to await a loop: When the engine reaches the await part, it sets a timeout and halts the execution of the async function. Just thought I'd post my two cents here as well. Obviously you need async/await support for that. If using ES6, you could use a for loop to achieve this: It declares i for each iteration, meaning the timeout is what it was before + 1000. Choosing Java instead of C++ for low-latency systems, Podcast 315: How to use interference to your advantage – a quantum computing…, Opt-in alpha test for a new Stacks editor, Visual design changes to the review queues. https://stackoverflow.com/questions/4548034/create-a-pause-inside-a-while-loop-in-javascript/4548079#4548079. Since ES7 theres a better way to await a loop: // Returns a Promise that resolves after "ms" Milliseconds const timer = ms => new Promise(res => setTimeout(res, ms)) async function load { // We need to wrap the loop into an async function for this to work for (var i = 0; i < 3; i++) { console.log(i); await timer(3000); // then the created Promise can be awaited } } load(); Adding days in a date using the Field Calculator.
