Is there any way to wait for a forloop to complete (without callback)...?

Question

I want to wait for a loop to complete...
Currently I'm doing it with callback....
Is there anything to do the same thing more elegantly...?

Answer 1

You can consider use promise with async and await

For example
function processForLoop() {
return new Promise(resolve => {
for(var i=0;i<100;i++) {
console.log(i)
}
resolve(i)
});
}

async function getForLoopOutput() {
var out = await processForLoop();
console.log("Resolve output = " + out); // get result from output of processForLoop()
}

getForLoopOutput();

Thank you bro....
But this is hand made...
Is there any dedicated logic to get the same thing?

Answer 3

What do you mean by hand make?
The function works on any delay callback as well since async is always ready to wait for the output from Promise.
