Convert NodeList to Array

If you run the document.querySelectorAll("p") function, it returns an array of DOM elements, the NodeList object. But this object does not have some array functions, such as sort(), reduce(), map(), filter(). To enable these functions, as well as other array primitives, you need to convert NodeList to an array. To convert, just use this function: [] .slice.call (elements):

var elements = document.querySelectorAll("p"); // NodeList var arrayElements = []. slice.call (elements); //Now converted to array var arrayElements = Array.from(elements); //Another way to convert NodeList to array Thank you for reading!
