$('li') in jQuery

Question

$('li') in jQuery return something like [.........].
Is it an array ?

Answer 1

It returns an array of elements which are not jquery objects.

If someone is wondering how jquery managed to add custom functions to the array for example:

$("li").hide()

The functions are assigned to __proto__ property

var array = document.getElementsByTagName("li")

array.__proto__.hide = function() {
for(let a = 0; a < this.length; a++) {
this[a].style.display = "none"
}
}

array.hide()
