jQuery is a JavaScript library  that can be used for communicating  selecting html elements  attaching event listeners  animations etc   with the DOM  creating and consuming AJAX requests  as well as other things in a more easier way rather than using plain JavaScript  jQuery is written in JavaScript  It should be mentioned that browsers parse only HTML  CSS and JavaScript files  Hence  all JavaScript libraries frameworks  jQuery  Knockout  Angular  are written in JavaScript or in languages like TypeScript that transconpiles to JavaScript  e g  Angular 2   They provide you the opportunity to write less lines of codes or to create interfaces following patterns like MVC  e g  Angular   MVVM  e g  Knockout  as well as other patterns  but under the hood  they are all result in a JavaScript file    An example in order to understand why using jQuery you write less do more is the following   Let we have the following input element   lt input id  button1  type  button  value  clickMe   gt     Also  let that we want when someone clicks on the button to be notified through an alert box showing to the user a  Hello  message   If we had to do this using plain JavaScript  we would have written the following   document getElementById  button1            addEventListener  click   function                 alert  Hello                  On the other hand  if we were using jQuery  we would had achieved the same result by just writing this       button1   click function         alert  Hello           Using jQuery makes things more clear than using plain JavaScript for the same purpose   write less do more is jQuery s moto   Furthermore  jQuery handles pretty well the theme of browser compatibility  you can use their API pretty easily without wondering too much as if you should do in case of using plain JavaScript   Below I have added snippets for the code above    x000D   x000D  document getElementById  button1   x000D           addEventListener  click   function     x000D              alert  Hello    x000D              x000D   lt input id  button1  type  button  value  clickMe   gt  x000D   x000D   x000D     x000D   x000D      button1   click function    alert  Hello        x000D   lt script src  https   ajax googleapis com ajax libs jquery 2 1 1 jquery min js  gt  lt  script gt  x000D   lt input id  button1  type  button  value  clickMe   gt  x000D   x000D   x000D

jQuery is a JavaScript library   Read   wiki-jQuery  github  jQuery vs  javascript   Source  What is JQuery      Before JQuery  developers would create their own small frameworks    the group of code  this would allow all the developers to work around all   the bugs and give them more time to work on features  so the   JavaScript frameworks were born  Then came the collaboration stage    groups of developers instead of writing their own code would give it   away for free and creating JavaScript code sets that everyone could   use  That is what JQuery is  a library of JavaScript code  The best   way to explain JQuery and its mission is well stated on the front page   of the JQuery website which says       JQuery is a fast and concise JavaScript Library that simplifies HTML   document traversing  event handling  animating  and Ajax interactions   for rapid web development       As you can see all JQuery is JavaScript  There is more than one   type of JavaScript set of code sets like MooTools it is just that   JQuery is the most popular     JavaScript vs JQuery     Which is the best JavaScript or JQuery is a contentious discussion     really the answer is neither is best  They both have their roles I   have worked on online applications where JQuery was not the right tool   and what the application needed was straight JavaScript development    But for most websites JQuery is all that is needed  What a web   developer needs to do is make an informed decision on what tools are   best for their client   Someone first coming into web development does   need some exposure to both technologies just using JQuery all the time   does not teach the nuances of JavaScript and how it affects the DOM    Using JavaScript all the time slows projects down and because of the   JQuery library has ironed most of the issues that JavaScript will   have between each web browser it makes the deployment safe as it is   sure to work across all platforms       JavaScript is a language  jQuery is a library built with JavaScript to help JavaScript programmers who are doing common web tasks    See here
