Runs an array of promises in series.
Array.prototype.reduce()
to create a promise chain, where each promise returns the next promise when resolved.const runPromisesInSeries = ps =>
ps.reduce((p, next) => p.then(next), Promise.resolve());
const delay = d => new Promise(r => setTimeout(r, d));
runPromisesInSeries([() => delay(1000), () => delay(2000)]);
// Executes each promise sequentially, taking a total of 3 seconds to complete
