[GitHub] [netbeans] brettryan opened a new issue, #4757: JavaScript to support "for await of"

[GitBox <gi...@apache.org>]

brettryan opened a new issue, #4757:
URL: https://github.com/apache/netbeans/issues/4757

   ### Description
   
   As a javacript developer I would like to have support for [for await...of (ECMAScript specification)](https://tc39.es/ecma262/multipage/ecmascript-language-statements-and-declarations.html#sec-for-in-and-for-of-statements) so that I can write asynchronous iterators using the `for` keyword.
   
   Taken from the [MDN for await...of](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for-await...of) example, the following for await statement uses an asynchronous iterator to produce its output
   
   ```javascript
   async function* foo() {
     yield 1;
     yield 2;
   }
   
   (async function() {
     for await (const num of foo()) {
       console.log(num);   // expected output: 1
       break;              // closes iterator, triggers return
     }
   })();
   ```
   
   Presently this produces the following error message:
   
   > Expected ( but found await
   
   
   ### Use case/motivation
   
   Working with NodeJS applications such as AWS Lambda works with a lot of async code. Having native support for this within NetBeans IDE provides a better developer experience.
   
   I am willing to contribute with guidance.
