Скачать или смотреть Javascript Array.from() is very underrated!!!

Array.from() is a powerful method introduced in ES6 that allows you to create arrays from array-like or iterable objects (like strings, NodeLists, sets, and more). It provides a simple way to convert these collections into true arrays, enabling the use of array methods on them.

You can convert any iterable object into an array:
let mySet = new Set([1, 2, 3]);
let arr = Array.from(mySet);
console.log(arr); // [1, 2, 3]

You can also pass a mapping function as the second argument:
let numbers = '12345';
let arr = Array.from(numbers, num =(arrow here) Number(num) * 2);
console.log(arr); // [2, 4, 6, 8, 10]

Array.from() shines when you’re working with objects like NodeLists or arguments, which don’t have array methods by default. It’s also handy for cloning arrays and applying transformations in one go, providing both flexibility and performance.
