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)

example
-------

function tst() {
setTimeout(()=>{console.log('setTimeout-0')},0)
////
pbest_effort(() => console.log("best_effort queue level 1:",111),1); //----pbest_effort only work on nodejs
pbest_effort(() => console.log("best_effort queue level 1:",222),1); //----pbest_effort only work on nodejs
pbest_effort(() => console.log("best_effort queue :",100)); //----pbest_effort only work on nodejs
pbest_effort(() => console.log("best_effort queue :",200)); //----pbest_effort only work on nodejs
////
plow(() => console.log("low queue level 0 :",'X'))
plow(() => console.log("low queue level 0 :",'Y'))
////
plow(() => console.log("low queue level 1 :",'lowA:1'),1)
plow(() => console.log("low queue level 1 :",'lowB:1'),1)
phigh(()=>console.log("high queue level 1 :",'M'),1)
phigh(()=>console.log("high queue level 1 :",'N'),1)
////
phigh(() => {console.log("high queue level 0 :",'c')});
phigh(() => {console.log("high queue level 0 :",'d')});
/////
console.log('\nbegin!')
}
