An example of a for-each loop implementation with callbacks using the async/await pattern. This works in the browser and Node.js. Get the "request" method here https://gist.github.com/lmzach09/38d291edb90f64d338132824a9de35ce#file-request-js

forEachWithCallbackExample.js

const request = require('./request.js');

function forEachWithCallback(callback) {
    const arrayCopy = this;
    let index = 0;
    const next = () => {
        index++;
        if (arrayCopy.length > 0) {
            callback(arrayCopy.shift(), index, next);
        }
    }
    next();
}

Array.prototype.forEachWithCallback = forEachWithCallback;

const array = [1, 2, 3, 4, 5];

array.forEachWithCallback(async (el, i, next) => {
    const response = await request({
        method: 'GET',
        hostname: 'httpbin.org',
        path: '/get?myArg=' + el
    });

    const responseBody = JSON.parse(response.body);
    console.log(responseBody.args.myArg);
    next();
});
