Here is how to use the for..of loop to iterate an array and await inside the loop:
const fun = (prop) => { return new Promise(resolve => { setTimeout(() => resolve(`done ${prop}`), 1000); }) } const go = async () => { const list = [1, 2, 3] for (const prop of list) { console.log(prop) console.log(await fun(prop)) } console.log('done all') } go() You need to place the loop in an async function, then you can use await and the loop stops the iteration until the promise we’re awaiting resolves.
