I think it’s a useful convention for callbacks to come as the last argument to a function. This is usually the case with the Node.js API, for instance. So with that in mind: delay = (ms, func) -> setTimeout func, ms delay 1000, -> something param Granted, this adds the overhead of an extra function … Read more
Using setInterval or setTimeout You should pass a reference to a function as the first argument for setTimeout or setInterval. This reference may be in the form of: An anonymous function setTimeout(function(){/* Look mah! No name! */},2000); A name of an existing function function foo(){…} setTimeout(foo, 2000); A variable that points to an existing function … Read more
let timer: ReturnType<typeof setTimeout> = setTimeout(() => { … }); clearTimeout(timer); By using ReturnType<fn> you are getting independence from platform. You won’t be forced to use neither any nor window.setTimeout which will break if you run the code on nodeJS server (eg. server-side rendered page). Good news, this is also compatible with Deno!
EDIT: In summary, back in 2010 when this question was asked the most common way to solve this problem was to save a reference to the context where the setTimeout function call is made, because setTimeout executes the function with this pointing to the global object: var that = this; if (this.options.destroyOnHide) { setTimeout(function(){ that.tip.destroy() … Read more
Your sleep function does not work because setTimeout does not (yet?) return a promise that could be awaited. You will need to promisify it manually: function timeout(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } async function sleep(fn, …args) { await timeout(3000); return fn(…args); } Btw, to slow down your loop you probably don’t want … Read more
setTimeout(function() { postinsql(topicId); }, 4000) You need to feed an anonymous function as a parameter instead of a string, the latter method shouldn’t even work per the ECMAScript specification but browsers are just lenient. This is the proper solution, don’t ever rely on passing a string as a ‘function’ when using setTimeout() or setInterval(), it’s … Read more
