JavaScript setTimeout in for Loop for Performance Test Ask Question Asked 6 years, 6 months ago Modified 6 years, 6 months ago Viewed 266 times 0 I am trying to use setTimeout for a performance test using console.time () and console.timeEnd (). JetStream 2.1 is a JavaScript and WebAssembly benchmark suite focused on advanced web applications. They return objects instead of just ids for clearing. Differences between window and Node.js: setTimeout and setInterval are on the global object. boilerplate block (code will executed before every block and is part of the benchmark. it will be run before every test, and is not part of the benchmark.) 1. The nTimersToTime (msToRun) function would advance it by msToRun milliseconds. Instead of the timer running automatically, you would advance it manually. Ditch Jasmine's mock setTimeout and setInterval. Setup block (useful for function initialization. 1 Answer Sorted by: 38 The call to eFakeTimers () mocks every timer function with one that you must control. param1, …, paramN OptionalĪdditional arguments which are passed through to the function specified byĬonsole. Now, we're able to test the function's return value. The setTimeout()method takes two parameters: a function to be executed and a delay time in milliseconds. Note that in either case, the actual delay may be longer than intended see Reasons for delays longer than specified below.Īlso note that if the value isn't a number, implicit type coercion is silently done on the value to convert it to a number - which can lead to unexpected and surprising results see Non-number delay values are silently coerced into numbers for an example. Feb 23 Listen Share Improving Web Performance What’s a setTimeout() setTimeout()is a method in JavaScript that allows you to schedule a function to be executed after a specified amount of time has elapsed. You can use eFakeTimers() to enable fake timers to test setTimeout to implement the test cases you want. Is used, meaning execute "immediately", or more accurately, the next event cycle.
