What type of data does querySelectorAll return? [duplicate]

Answer 1

The Element method querySelectorAll() returns a static (not live) NodeList representing a list of the document's elements that match the specified group of selectors.

For the differences please visit: Difference between HTMLCollection, NodeLists, and arrays of objects

You can use Spread syntax to make that as an array:

var obj1 = {
  fname: "Mirajul",
  lname: "Momin",
  age: 24
};
console.log(obj1.length);
var paraList = [...document.querySelectorAll("p")];
console.log(paraList.length);
console.log(Array.isArray(paraList));
