They say V8 engine is a proper Javascript ES5 engine. Does it support ES5 features like Promise?

推荐答案

App脚本V8可以识别新的函数定义格式，例如:

Apps script V8 recognizes the new function definition formats, for example:

let letAsyncFunction = async function() { //Your logic here }

它异步地返回函数求值的结果，就像一个Promise.

It asynchronously returns the result of the function evaluations, pretty much like a Promise.

换句话说，当调用函数async时，它将返回一个Promise.此外，await用于调用异步函数并等待其解析或拒绝

In other words, when the function async is called, it returns a promise. Also await is used for calling an async function and wait for it to resolve or reject
