Array.from(document.querySelectorAll(".ClassName")).forEach(function(element) {
//Stuff
});//create an array like so:
var colors = ["red","blue","green"];
//you can loop through an array like this:
for (var i = 0; i < colors.length; i++) {
console.log(colors[i]);
}console.log(Array.from('foo'));
// expected output: Array ["f", "o", "o"]
console.log(Array.from([1, 2, 3], x => x + x));
// expected output: Array [2, 4, 6]
const arrayOfDigits = numToSeparate.toString().split("");// Create an array based on a property of DOM Elements
const images = document.getElementsByTagName('img');
const sources = Array.from(images, image => image.src);
const insecureSources = sources.filter(link => link.startsWith('http://'));//Array from javascript
// The Array.from() static method creates a new, shallow-copied Array instance from an array-like or iterable object.
// Array from a String
Array.from('foo');
// [ "f", "o", "o" ]
// Array from a Set
const set = new Set(['foo', 'bar', 'baz', 'foo']);
Array.from(set);
// [ "foo", "bar", "baz" ]
// Array from a Map
const map = new Map([[1, 2], [2, 4], [4, 8]]);
Array.from(map);
// [[1, 2], [2, 4], [4, 8]]
const mapper = new Map([['1', 'a'], ['2', 'b']]);
Array.from(mapper.values());
// ['a', 'b'];
Array.from(mapper.keys());
// ['1', '2'];
// Using an arrow function as the map function to
// manipulate the elements
Array.from([1, 2, 3], x => x + x);
// [2, 4, 6]
