Pseudo-arrays types in JavaScript

Pseudo-arrays come in various types. The type depends on the method of obtaining.

In the following example, we will get a collection of one type:

let elems = document.querySelectorAll('p'); console.log(elems); // NodeList

And in the next example we will get a collection of another type:

let elems = document.getElementsByTagName('p'); console.log(elems); // HTMLCollection

Check what type of collection will be in the childNodes property.

Check what type of collection will be in the children property.
