I felt really stupid when I wrote this yesterday, which you would NEVER do in C++:
Promise.allSettled(promises, (results) => {
for(i in results) {
if(results[i].status === "fulfilled") {
....
}
}
}
Like really? We want the processor to test for equality 9 times for "f", "u", "l", "f", "i", "l", "l", "e", "d"? Or is there some built-in optimization for this?
Or should I do this, which feels hacky, but reduces it to 1 equality test?
const FULFILLED === "f";
Promise.allSettled(promises, (results) => {
for(i in results) {
if(results[i].status[0] === FULFILLED) {
....
}
}
}
