nv-facutil-simple-microq

• wrap of queueMicrotask AND process.nextTick AND Promise.prototype.finally,apply
• phigh high priority micro task
• plow low priority micro task
• pbest_effort lower priority micro task , only work in nodejs

install

• npm install nv-facutil-simple-microq

usage

       const {phigh,plow,pbest_effort} = require("nv-facutil-simple-microq")

       in each high/low level :
           first high priority
           then  low  priority
           ---> then next high/low level
           
       when all high/low  task finished:
       
       in each best_effort level :
              best_effort 
              ---> then next best_effort level  

       final:
          ---> goto next-loop-macro-task, such as setTimeout(0)
