What is JavaScript & jQuery?

JavaScript is a programming language that allows individuals to make web pages interactive and control media, and jQuery is a JavaScript library that helps individuals use JavaScript to simplify web tasks. All code written in jQuery is converted to JavaScript internally. jQuery is one of the longest-running JavaScript libraries, and 98% of websites use JavaScript as a client-side programming language. In this section, you’ll learn more about JavaScript and jQuery and how to understand them. Once an individual understands jQuery and JavaScript, they can decide how to add these skills to their professional toolbox.

What Can You Do with JavaScript & jQuery?

Individuals can use JavaScript and jQuery for many purposes. JavaScript is used on the client side and the server side. It allows individuals to make web pages interactive and is mainly for web applications and web browsers. JavaScript is used for showing or hiding information with a button, changing the color of a button, zooming in or out, playing audio and video, displaying animations, or using a drop-down hamburger menu. It is also used to create browser games and web and mobile apps.

jQuery is not a programming language but a tool to facilitate web development in JavaScript. Individuals can even use any JavaScript editor to write jQuery, such as Notepad, Visual Studio, Eclipse, or Ultra edit. jQuery can be used to develop Ajax-based applications, to make code simple and reusable, to simplify the traversal of HTML DOM tree, and to perform animation and ajax support in web applications. jQuery also helps individuals to make flash-like animated applications. Using jQuery, individuals only need to know JavaScript and HTML to create animations. Web designers can use many impressive effects to make their designs more elegant. 

How Do You Download/Get JavaScript & jQuery? How Much Does it Cost?

When using JavaScript, there are just a few simple steps individuals need to take. Programmers can utilize JavaScript in a web browser, so it doesn’t need to be downloaded and installed. If a browser supports JavaScript, it will be built into the browser and turned on by default. This automaticity means that individuals won’t need to change their browser settings unless they don’t want to run JavaScript. Many JavaScript downloads are free, so there is no need to pay for scripts written in JavaScript. It is essential to obtain JavaScript from sites that offer it for free and not just copy scripts from any place. 

There is a step-by-step process to download jQuery and more than one way to start using it. Individuals can download the jQuery library from jQuery.com or include jQuery from a CDN, such as Google. The two versions available for download are the production version, which is for live websites, and the development version, which is for testing and development. Individuals can download both versions from jQuery.com Jquery is free to use and promotes simplicity. 

What Are the Benefits of Learning JavaScript & jQuery?

Reasons abound as to why you should learn JavaScript and jQuery. Programmers should learn several languages, as there is no such thing as knowing too many languages. One of the most commonly used languages is JavaScript. JavaScript is a great language to learn, as it is growing exponentially. 

JavaScript was first created in 1995 and is a programming language that allows individuals to make complex things on websites. It is perfect for those just starting with programming and will enable individuals to expand their skill set. Through JavaScript, individuals can create visual effects and other aesthetically pleasing features. It is a valuable tool for game designers and can increase one's career potential. 

jQuery is used to build interactivity in websites and allows Developers to use code snippets to do traversal on the page or make changes to different elements using JavaScript. One of the most basic uses for jQuery is adding functionality to a website's button. It provides all the tools needed to simplify this process. Those working at a small business with legacy code will likely use jQuery. It helps individuals to understand the foundational level of what JavaScript is doing on a page.

A Brief History of JavaScript & jQuery

Although JavaScript and jQuery have been around for several years, JavaScript was invented before jQuery. JavaScript was invented in 1995 by a man named Brendan Eich. When Eich first created the web, web pages had no capability for dynamic behavior and interactivity. This static and inconvenient design spurred the web development community to eliminate this restriction. 

Once it was released, more browsers began adding JavaScript support, but many failed to consider JavaScript as a serious programming language for years. When it was first released, riddled with performance and security issues, no alternative existed. Years later, Ryan Dahl released Node.js. Node.js allowed JavaScript code to run outside a browser and freed up the language to run more smoothly. This development ultimately led to JavaScript’s popularity. 

jQuery was designed in 2006 by John Resig. John created the first jQuery version in 2005 and publicized it in 2006. The release occurred at a tech event called BarCampNYC. jQuery was developed by John Resig out of frustration and a desire to solve problems with writing cross-browser code. Because of the lack of standardization, developers had to worry about different browser behaviors, which made their work inefficient. jQuery fixed this problem and revolutionized how the world read and wrote JavaScript. Resig focused on developing tools to manipulate HTML in one DOM, which became jQuery.

Comparable Applications/Programming Languages/Fields

Most Web Developers are very familiar with JavaScript and may wonder if there are any alternatives to JavaScript. There are many, specifically for regular scripts or programs. Some popular programming languages that can replace JavaScript include Python, C, C++, Perl, Smalltalk, and Ruby. 

The alternative a Web Developer chooses depends on their purpose. Those working in back end development may choose Python, Ruby, Kotlin, or PHP. For front end development, Dart is an object-oriented programming language similar to C. For mobile development, individuals may use React Native– also an open-source framework– when creating native apps to go cross-platform. Python is one of the most popular JavaScript alternatives, but it cannot help with front-end development. 

There are also alternatives to jQuery. React is the best alternative to jQuery because it fills most developer requirements. Vue is another alternative and a JavaScript framework for creating user interfaces for web apps. Umbrella JS is another option that allows individuals to use native JavaScript methods.
