Difference between Javascript and jQuery Selectors

Finding HTML elements using ID, Classname, Tag, CSS Selectors

Javascript

var val = document.getElementById("id1"); //using id
var val = document.getElementsByClassName("cls"); //using classname
var val = document.getElementsByTagName("p"); //using tag name
var val = document.querySelectorAll("p.cls"); //using selector

jQuery

var val =$("#id1"); //using id
var val = $(".cls"); //using classname
var val = $("p"); //using tag name
var val = $("p.cls"); //using selector
