lmzach09 / foreach-with-timeout-example.js

Created August 21, 2019 00:05

An example of a JavaScript for-each loop that has a timeout inside. The results are not what you'd expect if you came to JS from Python.

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

	array.forEach((el, i) => {
	setTimeout(() => {
	console.log(el);
	}, 1000);
	});

lmzach09 / foreach-with-callback.js

Created August 21, 2019 00:09

Give your JavaScript Arrays a built-in method for looping over members in a synchronous fashion.

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

lmzach09 / 1-for-each-with-promise.js

Last active September 28, 2022 16:29

Implementation of a for-each loop in JavaScript that works with callbacks. The next iteration in the loop does not start until the previous iteration's callback gets called.

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

	array.forEachWithCallback((el, i, next) => {
	request({
	method: 'GET',
	hostname: 'httpbin.org',
	path: '/get?myArg=' + el
	}).then((res) => {
	const responseBody = JSON.parse(res.body);
	console.log(responseBody.args.myArg);
