Demonstration of synchronously executed functions using reduce and promises

synchronousFunctions.js

let myArray = ["beans", "soup", "peanuts", "artichokes"];

myArray.reduce((promise, item) => {
    return promise.then(() => {
        return itemsPromise(item);
    });
}, Promise.resolve()).then(() => {
    console.log("ALL DONE");
})

let itemsPromise = (item) => {
    console.log("Item: ", item);
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve();
        }, 2000);
    });
}
