I te tauira tauira i raro ake nei, ka whakatinanahia e maatau te matawaka ngawari rawa kia waiho ma te 100 milliseconds e whakaoho.

            var timmer = new Worker(
    URL.createObjectURL(
        new Blob(
            [

Te whakamahi paerewa

I roto i te tauira i runga ake nei, i hangaia e matou he wahitau ma te whakamahi i te createObjectURL. Na te mea he maama noa te waehere e hiahiatia ana e maatau, ka tino poto tenei tikanga Mena he uaua ake te waehere o te mahi hei mahi maatau, ka taea e taatau te tuhi wehe i te mahi hei konae js motuhake. Mo nga korero taipitopito, tirohia te waehere e whai ake nei. He nui ake nga korero whakamohio, ka taea e koe te korero ki nga rauemi tohutoro kei runga ake o te tuhinga.
