Put your bash code in functions
- _bxg1 6y agoThis is one reason I have reservations about async/await syntax in JavaScript. Promises are parallel by default; you have to go out of your way to make them "synchronous". The synchronous way of doing things may be clunky, but I'm not so sure that isn't a feature. In my experience it's uncommon that synchronicity is what you want. But with async/await, you're doing things sequentially by default. This means it's really easy to accidentally make things take longer than they need to.
- furstenheim 6y agoParallelizing is plain simple "await Promise.all([first, second])" Problem is doing some serious synchronization like n at a time or similar. Those things are better of with callbacks
- _bxg1 6y agoThat's still clunkier than await first await second So lots of people might not ever think to do it the other way. If you don't have intimate knowledge of how promises work and what async/await really do, you might not even realize that this is wrong.
- furstenheim 6y agoYou can always move it to a variadic function and do await parallel(first, two) If your concern is clunkiness, I'm curious about callbacks, they're definitely more complex to use. I understand your point that not knowing how promises work can lead to not optimizing them, but going from one to the second can easily done on another iteration. On the other hand, not being capable with callbacks can easily lead to (callback) hell, then you need to first fix the mess, then optimize.
