jQuery is a brilliant piece of software created by John Resig, used by a huge eco-system of plug-ins.

A lot of web developers remember the time when jQuery was the de-facto standard library to build anything in the browser.

It helped a lot to do things without worrying about the quirks and the inconsistencies of the browsers:

• Perform Ajax requests
• Query the DOM to show or hide elements in the page
• Animate elements… how sweet was $('mySelector').fadeOut()?
• And so many other things… jQuery was the Swiss Army knife of web developers!

Let’s not forget the nice documentation too.

But things have changed, browsers have improved a lot, and they follow new standards… that have been inspired by the jQuery API: document.querySelector() for example, is close to jQuery “selectors”.

Nowadays web applications usually rely on front-end libraries and frameworks like React, Vue.js or Angular that flavor different patterns.

To help with the transition to the post-jQuery era, You don’t need jQuery, the project number one this week, shows how to do a lot of common tasks using plain JavaScript, without any library.

Also we should mention a similar project: You might not need jQuery.
