Here's a quick plug for my `prfun` library (https://github.com/cscott/prfun) which implements this as `Promise.delay(1000)`.
API at: https://github.com/cscott/prfun#promisedelaydynamic-value-int-ms--promise You can also do `return somepromise.delay(100)` which resolves to the same value as `samepromise`, just 100 ms later. --scott On Wed, Feb 3, 2016 at 4:03 PM, Andrea Giammarchi < andrea.giammar...@gmail.com> wrote: > Chiming in just to underline that setTimeout and setInterval accepts extra > arguments since about ever so that the following is eventually all you need. > > ```js > new Promise(r => setTimeout(r, 1000)); > new Promise(r => setTimeout(r, 1000, "some value")); > ``` > > Best Regards > > > > > On Wed, Feb 3, 2016 at 8:51 PM, JD Isaacks <j...@jisaacks.com> wrote: > >> I think it would be super useful to be able to do something like: >> >> Promise.after(1000).then( /* cb */ ); >> >> and have the promise resolve after 1000 milliseconds. >> >> The promise would just resolve with the same value (in this case 1000) >> but could easily delay resolving another value like so: >> >> Promise.after(1000).then(() => "other value"); >> >> instead of currently having to use a setTimeout: >> >> new Promise(resolve => setTimeout(() => resolve("some value"), 1000)); >> >> I believe Promise.after would be so much more readable and useful. >> >> I am not sure if the name `after` is the best name, `wait`, `when`, >> `sleep` are possible names or maybe there is a better name I haven't even >> thought of. >> >> _______________________________________________ >> es-discuss mailing list >> es-discuss@mozilla.org >> https://mail.mozilla.org/listinfo/es-discuss >> >> > > _______________________________________________ > es-discuss mailing list > es-discuss@mozilla.org > https://mail.mozilla.org/listinfo/es-discuss > >
