How do you select elements in the DOM?

Method	Returns
`getElementById("id")`	One element
`querySelector("css")`	First match of a CSS selector
`querySelectorAll("css")`	All matches (NodeList)
`getElementsByClassName("c")`	Live HTMLCollection of a class

const a = document.getElementById("title");
const b = document.querySelector(".note");
const all = document.querySelectorAll("p.note");

querySelector and querySelectorAll are the most flexible, because they use CSS selectors. See HTML DOM.
