Array Async

Installation

npm install --save rescript-types-array-async

Summary

let arr = [1, 2, 3]
let asyncFn = (n: int) => {
  Console.log(n)
  Promise.resolve(n+1)
}

// With Promise.all Console.log will not output the array items in order
let resultAll = Promise.all(arr->Array.map(asyncFn))
// -> result: [2, 3, 4]
// -> stdout: [2, 4, 3]

// With ArrayAsync.map will output the array items in order
let result = ArrayAsync.map(arr, asyncFn)
// -> result: [2, 3, 4]
// -> stdout: [2, 3, 4]
