# Similarities with arrays in JavaScript

Let's see how pseudo-arrays are similar to regular arrays.

## Indices

The elements of a pseudo-array, like the elements of a regular array, can be accessed by their index:

`console.log(elems[0]); console.log(elems[1]); console.log(elems[2]);`

## Length

You can also find out the number of elements using the `length` property:

`console.log(elems.length);`

## Loop

It is possible to loop through the elements of a pseudo-array:

`for (let elem of elems) { console.log(elem); }`

## Practical tasks

Paragraphs are given:

`let elems = document.querySelectorAll('p');`

Check for the variable `elems` the described possibilities of pseudo-arrays.
