How to use map to implement Asynchronous traversal in JavaScript

This article is about how to use JavaScript to implement asynchronous traversal. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Map can also be traversed asynchronously

Do you think it is inconvenient to only use for to perform asynchronous operations? In fact, map can also perform asynchronous operations, but it needs to be used together with the new method of Promise.

const arr = [1,2,3,4,...] const queue = arr.map(async item => { return item + 1;})Promise.all(queue).then(newArr => console.log(newArr))

This way we can also use asynchronous operations in map
