Although pseudo-arrays are similar to arrays,
they are still ordinary objects. They don't
have array methods
like forEach
, join
, slice
.
For example, if you try to use slice
to DOM elements, then it just won't work:
console.log(elems.slice(1, 3)); // there will be an error
Paragraphs are given:
let elems = document.querySelectorAll('p');
Check if the array methods will work
for the variable elems
.
