use document.getElementById is core JavaScript
document.getElementById("id-name-here")
now a days because of use of jQuery like JavaScript Library , people very rarely use core JavaScript .

use document.querySelector
it work with class
var qs = document.querySelector(".class-name");
it work with id
var qs = document.querySelector("#id-name");
it work with nested element
var qs = document.querySelector("span.info.main");
it work almost same as jQuery selector do
but document.querySelector Returns the first Element for given selection search. it good for id because for particular id its only one element but for classname and other selector it had more than one element
for that document.querySelectorAll is good
document.querySelectorAll return list of element .
