how to use await in for loop code example
Example 1: async for loop
(async function loop() {
for (let i = 0; i < 10; i++) {
await new Promise(resolve => setTimeout(resolve, Math.random() * 1000));
console.log(i);
}
})();
Example 2: async foreach
async function asyncForEach(array, callback) {
for (let index = 0; index < array.length; index++) {
await callback(array[index], index, array);
}
}
asyncForEach([1, 2, 3], async (num) => {
await waitFor(50);
console.log(num);
})
