This vanilla ES6 function async
allows code to yield
(i.e. await
) the asynchronous result of any Promise
within. The usage is almost identical to ES7's async/await
keywords.
async/await
control flow is promising because it allows the programmer to reason linearly about complex asynchronous code. It also has the benefit of unifying traditionally disparate synchronous and asynchronous error handling code into one try/catch block.
This is expository code for the purpose of learning ES6. It is not 100% robust. If you want to use this style of code in the real world you might want to explore a well-tested library like co, task.js or use async/await
with Babel. Also take a look at the official async/await
draft section on desugaring.

* This sketch sends ads1115 current sensor data via out over serial port. | |
* It needs the following libraries to work (besides the esp8266 standard libraries supplied with the IDE): | |
* | |
* - https://github.com/adafruit/Adafruit_ADS1X15 | |
* - https://github.com/adafruit/Adafruit_SSD1306 | |
* - https://github.com/adafruit/Adafruit-GFX-Library | |
* | |
* The above libraries can be directly installed via the Arduino IDE | |

The final solution !!
Since the first version of pthreads, PHP has had the ability to initialize Worker threads for users. Onto those Worker threads are stacked objects of class Stackable for execution concurrently.
The objects stacked onto workers do not have their reference counts changed, pthreads forces the user to maintain the reference counts in userland, for the extremely good reason that this enables the programmer to keep control of memory usage; and so, execute indefinitely.
This is the cause of much heartache for newcomers to pthreads; if you do not maintain references properly you will, definitely, experience segmentation faults.
