This article will explain in detail how to realize array deconstruction in ES6. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Array deconstruction

Sometimes you put multiple values returned by a function in an array. We can use array deconstruction to get each of these values.

1 numerical exchange let param1 = 1 param1 param2 = 2 swap swap & param2 each others values [param1, param2] = [param2, param1]; console.log (param1) / / 2console.log (param2) / / 12 receive multiple results returned by the function

In the following code, we get a post from / post and then get the relevant comments in / comments. Since we are using async/await, the function puts the return value in an array. After we deconstruct the array, we can assign the return value directly to the corresponding variable.

Async function getFullPost () {return await Promise.all ([fetch ('/ post'), fetch ('/ comments')]);} const [post, comments] = getFullPost (); this is the end of the article on "how to deconstruct arrays in ES6". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
