Javascript's setTimeout can sort an array, how?

#javascript #node #discuss #beginners

setTimeout function of the Web API's with Javascript; can sort an array.

Example:


[111,20,13,4,544,32,12,414,123].forEach((item) => {

   setTimeout(()=> console.log(item), item);

});

The same works for negative as well,
Example:

let arr = [10, -100, 650, -25, 5, -50];

const min = -Math.min(...arr)

arr.forEach((item) => {
  setTimeout(() => console.log(item), item + min);
});

Any guesses how?
Of course, not an efficient way to do it.

Clue: Call-Stack and Web API's

I saw this on r/ProgrammerHumor the other day and initially thought it was a gimmick but then I reproduced it and yep it works. I did find some possible explanations here stackoverflow.com/questions/526798...
