# concurrency_js

a js file that implement concurrency async operation which could limit concurrency nums.

usage :

```

C.add(asyncFuncPrototype,...args)

C.wait().then(()=>{console.log("all done")})

```

remember to resolve() in your async function other wise queue will be blocked.

default concurreny num is 5

```

C.setMaxRunning(10) to change concurrency num.

```

// look demo  for more detail.

```

function demo() {

    function timeToPrint(t) {

        return new Promise((resolve, reject) => {

            setTimeout(() => {

                console.log(t)

                resolve()

            })

        })

    }

    setTimeout(() => {

        for (let i = 1; i < 100; i++) {

            let t = i

            C.add(timeToPrint, t)

        }

    }, 100)

    setTimeout(() => {

        for (let i = 1; i < 100; i = i + 5) {

            let t = i

            C.add(timeToPrint, t)

        }

    }, 2000)

    setTimeout(() => {

        for (let i = 1; i < 100; i = i + 3) {

            let t = i

            C.add(timeToPrint, t)

        }

    }, 5000)

    C.wait().then(() => {

        console.log("all done")

    })

}
