Syntax

const arr2 = Array.from(arguments);

If a value is iterable (as all Array-like DOM data structure are by now), you can also use the spread operator (…) to convert it to an Array:

const arr1 = [...'abc'];
    // ['a', 'b', 'c']
const arr2 = [...new Set().add('a').add('b')];
    // ['a', 'b']
