//To obtain a NodeList of all of the <p> elements in the document:
const matches = document.querySelectorAll("p");
//This example returns a list of all <div> elements within the document with a class of either note or alert:
const matches = document.querySelectorAll("div.note, div.alert");
//Here, we get a list of <p> elements whose immediate parent element is a <div> with the class highlighted and which are located inside a container whose ID is test.
const container = document.querySelector("#test");
const matches = container.querySelectorAll("div.highlighted > p");Copyright © 2021 Codeinu
