array-asyncify

Issue

We cannot use async function graceful in array methods such as filter,map,reduce and so on.

So the following code do not work
``javascript
let a=[1,2,3]
a.map(async (e)=>{
//some async operations
//await ...
return e+1
})
.filter(async (e)=>{
//some async operations
return e%2===0
})
`

Resolution

`javascript
const { asyncify } = require("array-asyncify")
let delay = (t) => new Promise(res => setTimeout(res,t))
console.log("Example:");
(async () => {

let a = asyncify([1, 2, 3])
console.log("ret:")
let ret = await a
.map(async (e) => {
await delay(100);
return e + 1
})
.map(async (e) => {
await delay(100)
return e * 2
})
console.log(ret)

try {
let b = asyncify([1, Promise.resolve(2), 3])
console.log("sum:", await b.reduce(async (p, n) => {
console.log("p,n", p, n)
return p + n
}))
} catch (e) {
console.log(e)
}


})()

``

asyncify other method.
