    jQuery is a quick, tiny, feature-rich, and cross-platform JavaScript library. It is created to ease the client-side scripting of HTML. It operates in very secure browsers by straightforward APIs like HTML document manipulation and traversal, event handling, animation, and Ajax. The primary purpose of jQuery is to make JavaScript interactive as well as attractive on the website. jQuery is cross-platform and maintains various kinds of browsers. It consists of many simple tasks that require multiple lines of JavaScript code for accomplishing and combine them into programs that can be summoned by a single line of the code when it is necessary. It is also advantageous for simplifying many complex facts from JavaScript, like AJAX calls and DOM manipulation.

    jQuery Features

    The following are the essential features of jQuery.

    • DOM manipulation
    • Effects and Animations
    • DOM element selection
    • HTML manipulation
    • CSS manipulation
    • HTML event methods
    • Utilities
    • AJAX
    • Extensibility through plug-ins
    • JSON Parsing

    Requirement of jQuery

    There is always a question of why we require jQuery and how powerful it is to make a difference compared to AJAX or JavaScript. So here is an answer:

    • It is rapid and noticeable.
    • It enables users to write compatible UI codes in at least two lines.
    • It improves the performance of the application.
    • Fit web applications for the browser can be created.
    • It uses new features for every new browser.
    • So, we can say that jQuery is very popular and extensible for most of the JavaScript frameworks, and most of the prominent companies use jQuery. Examples of companies are Microsoft, Google, IBM, and Netflix.

    jQuery Plugins

    As useful as jQuery is to simplify individual functions, it can be extended out even more efficiently in the form of plugins or collections of JS code from the jQuery library that combines together those individual functions then create a robust website features or tools. As we know that plugins are created through jQuery users based on the code in a jQuery library. It can be shared publicly online. Plugins can be detected in many places, those detected on the official jQuery UI (User Interface) repository can be considered quality work since they are curated by the professional community of jQuery. For providing a closer look at what else jQuery can be used for, here are 10 jQuery plugins available from the jQuery site.

    1. EFFECT

    The effect is a simple jQuery plugin that allows you to assign several animation effects to an element on the web page. By pressing the assigned button with the needed effect selected will result in the page element for behaving in different ways: bounce, disappear in a folding pattern, or slide.


    AJAX is one of the JavaScript-related functions that jQuery code can simply for web developers. AJAX calls are related to pulling content from the server and loading it on the web page so that things on that particular page can change without a user reloading the page. This plugin utilizes AJAX so that all additional content can appear on the page as any user scrolls down. You will notice this effect on blogs or other sites with a lot of written content where you do not have to click a "more" button to continue reading—the text simply loads as you scroll.


    This plugin jazzes up the standard header menus by animating each menu panel as a user scrolls past it with their mouse. As the mouse drags over, the individual's menu elements animate and pops out from its peers ade-out, etc.


    If you ever added a categorizing "tag" to the blog post then this plugin possibly helped with JavaScript code. This jQuery script which is taggingJS pulls from the JavaScript library and helps you for adding the tagging system to your website, a text bar where you can add relevant subject topics to the post, and help boost your indexability and ranking with search engines like Google.


    You know that the search bar on a big-time website like Google.com consists of completely autocomplete features that offer suggestions to finish what you are typing and You can add one of the JavaScript to your own project through this Autocomplete jQuery plugin. This particular example is coded to offer autocompleting suggestions of the programming terms . However, you can add your own list of autocomplete terms into the plugin.


    The plugin uses jQuery code for animating web page elements based on the positioning of the scroll bar of the user. Users can result in animation for happening as the page scroll or users can synchronize animation through the scroll position.


    If you ever used one of the menus online for uploading an image where you can drag the image into a box or click on the button for selecting the image file from your computer so that's another example of JavaScript and by extension, jQuery is used for. The Fine Uploader plugin offers web developers for skipping the steps of building the new uploader and uses jQuery tools for dropping a prebuilt one directly on your web page.

    8. blueimp GALLERY

    blueimp Gallery is a responsive (meaning it adjusts to display on desktop and mobile screens) image gallery that can be controlled by a desktop keyboard and mouse or by swiping on a phone or tablet. This plugin can be set to display either images or videos in a carousel format, and can also display images in a lightbox mode.

    9. SLICK

    Slick is another responsive image carousel plugin with different display options than the blueimp Gallery above. Slick allows for things like singular or multiple display formats, variable width displays, "lazy loading" (where the next image on the carousel fades into view as you scroll rather than displaying statically), and a single image fade in/out display option.

    10. SLIDER

    Another ubiquitous web page feature brought to you by JavaScript are the sliders used to adjust volume and other levels on a web page. This Slider plugin uses the jQuery library to assign numerical values on a horizontal bar. The slider can then be moved up and down the bar using a mouse or keyboard arrow keys.

    The benefits of jQuery

    • Easy to read: jQuery is easy to read because it supports the same JavaScript encoding.
    • Write less, do more: jQuery offers a rich set of features that increase the productivity of developers by writing less and more readable code.
    • Excellent API documentation: jQuery provides excellent online API documentation.
    • Browser Support: jQuery provides excellent browser support without writing any other code.
    • Unobtrusive: jQuery does not seem to allow separation of concerns by separating HTML and jQuery code.
