For reference purposes, we are going to say this code is stored in the test.js file. Let’s take a look at the following example and check a typical developer writing asynchronous logic inside the forEach callback without knowing the hidden problem he will face. Unless we have access to inspect the definition of the forEach method and understand what goes on behind, one way is to see an example of what happens when attempting to use forEach with async and await. Why Array.forEach() with async/await does not actually wait? This is when JavaScript shows one of those unexpected behaviors only developers who have noticed it, can share and advise to not use the forEach method with async and await because it doesn’t “await” or wait for a process to finish prior to continuing to the next process inside the callback function. If it is not in the documentation, why do you claim it is not meant for asynchronous programming? If we take a look at ECMA specifications defining the Array.forEach method, it doesn’t say anything about the method not designed for asynchronous operations. The official documentation for JavaScript is defined by Ecma International’s TC39, a group of JavaScript developers collaborating with the community to maintain and evolve the definition of JavaScript. While this site has become one of the main documentation references for JavaScript programmers, in theory, it is not the official documentation despite their excellent way to explain the concepts. If we verify the Mozilla MZN Web documentation and read through the () reference, you will find out there is a note saying forEach expects a synchronous function. Tie26 by Andreas Kupries (c 2004) - arraysync27 by Steve Redler IV (0 2006). Looking for an answer explaining why the forEach doesn’t work as expected when using it with async and await keywords is rather complex. But before addressing the Tcl programming model alternatives, it will be.
