Get number with Javascript

Question

Hello guys!
I have one question regarding number of items inside list in Html. I'll try to explain. In HTML i have
<li> some text </li>
<li> some text </li>
<li> some text </li>
So now I want to write function in JavaScript to get number of those list?! In this case that should be number 3. If I had 5 <li> that should show me 5 instead. I don't know if that is possible. I tried with id but didn't get it. I hope you understand my question.

Answer 1

just use
var x = document.querySelectorAll('li).length ;
now just print the 'x' varriable

Answer 2

Try,
let n = document.querySelectorAll("li").length
Edit: Abhay yeah, I mean to write querySelectorAll, thanks :-)

Answer 3

@vrintle you mean querySelectorAll not querySelector right?
You can try this as well ,anyway what vrintle did is what I should have thought but I really forgot about it and found some other way if you wanna try
for(i of document.body.children){
if(i.nodeName=="LI"){
}
}
