jQuery Tutorial: Using a JavaScript Library

Introduction

HTML, CSS, and JavaScript are the three fundamental languages of the web. We structure our websites with HTML, style them with CSS, and add interactive functionality with JavaScript. Most animations and any action that happens as a result of a user clicking, hovering, or scrolling are utilized with JavaScript.

jQuery is the “Write Less, Do More” JavaScript library. It is not a programming language, but rather a tool used to vastly simplify writing common JavaScript tasks. jQuery has the added benefit of being cross-browser compatibile, meaning you can be certain the output of your code will render as intended in any modern browser.

By comparing a simple “Hello, World!” example in both languages, we can see the difference of how JavaScript and jQuery are written.

document.getElementById('demo').innerHTML = 'Hello, World!'

$(‘#demo’).html(‘Hello, World!’)


As you can see, jQuery can be easier to read and write than plain JavaScript.

## Goals

This guide assumes no prior knowlegde of jQuery, will cover the following topics:

*   Learn how to install jQuery in a web project.
*   Learn the definitions of important web development concepts such as API, DOM, and CDN.
*   Review common jQuery selectors.
*   Learn about jQuery events and effects, and make some simple, functional examples.

## Prerequisites

Before you begin this guide you'll need the following:

*   A basic knowledge of HTML and CSS. You should already know how to set up a simple website, and have an understanding of CSS selectors such as ids, classes, and pseudo elements.
*   An understanding of the fundamentals of programming. While it is possible to begin writing jQuery without an advanced knowledge of JavaScript, familiarity with the concepts of [**variables and datatypes**](https://www.taniarascia.com/javascript-day-one/) as well as [**math and logic**](https://www.taniarascia.com/javascript-day-two/) will help significantly.

JavaScript vs jQuery — Learn DOM manipulation without using jQuery

jQuery has been the savior for so many new and coming Web Developers, including myself. If you wanted to learn Web Development back in the day, learning jQuery was an absolute given. This was mainly because jQuery took much of the cross-browser compatibility issues out and enabled developers to write code without having to worry about whether the features that they are implementing will work on all browsers.

But with improvements in browser standards and most of jQuery’s API’s integrated into JavaScript, jQuery has become a little redundant. Moreover, with native browser API’s it is so much easier to debug code, and being native, most of these API’s offer better performance than jQuery’s API’s. Besides, you will have one less library to add to your script imports. If you’re still not sold on parting with jQuery maybe this answer will help.

So, if you’re considering a move away from jQuery, I have compiled a list of common jQuery methods and API’s that people use, with their Vanilla JS alternatives (Vanilla JS is a fancy name for plain JavaScript code without the use of any libraries). Let’s dive in!

Querying the DOM

The bread and butter of jQuery is it’s amazing ability to query DOM elements. This is demonstrated below:

jQuery('div.home')

However, you can achieve the same thing with JavaScript using it **document.querySelector() **and document.querySelectorAll() methods. Below is their implementation.

Now Learn JavaScript Programming Language With Microsoft

icrosoft has released a new series of video tutorials on YouTube for novice programmers to get a hands-on renowned programming language — JavaScript.

This isn’t the first attempt by Microsoft to come up with video tutorials by beginner programmers. The company also has a series of YouTube tutorials on Python for beginners.

For JavaScript, Microsoft has launched a series of 51 videos as ‘Beginner’s Series to JavaScript,’ for young programmers, developers and coders who are interested in building browser applications using JavaScript. These video tutorials will also help programmers and coders to use relevant software development kits (SDKs) and JavaScript frameworks, such as Google’s Angular.


“Learning a new framework or development environment is made even more difficult when you don’t know the programming language,” stated on the Microsoft Developer channel on YouTube. “Fortunately, we’re here to help! We’ve created this series of videos to focus on the core concepts of JavaScript.”

It further stated — while the tutorials don’t cover every aspect of JavaScript, it indeed will help in building a foundation from which one can continue to grow. By the end of this series, Microsoft claims that the novice programmers will be able to work through tutorials, quick starts, books, and other resources, continuing to grow on their own.
