JavaScript vs. jQuery: What is the Difference?

A good understanding of JavaScript and jQuery is essential if you are new to web development. Although they are similar, comprehending the differences between JavaScript and jQuery will help you become familiar with JavaScript programming tools, frameworks, and libraries.

Let’s quickly go over the JavaScript programming language and how jQuery became part of the system.


Using JavaScript makes building interactive websites simple on both the client and server sides. It is a programming language that works with different web browsers. JavaScript links servers to websites and web applications; you can use JavaScript to make interactive web pages, browser games, and more. JavaScript can almost do everything from adding simple animations and effects to building a web app with complex functionality.

Additionally, JavaScript is an excellent choice for web development since it is widely used and supported. Because HTML, CSS, and JavaScript work together so well, learning the three is pretty much mandatory if you want to build anything interactive.

Furthermore, libraries and frameworks are components of JavaScript. JavaScript frameworks are comprehensive tools that help you shape and structure your website or online application, whereas JavaScript libraries are specialized tools for on-demand use.

You can enhance written HTML and JavaScript code to increase style, efficiency, and other valuable features. It is easier to construct JavaScript-based apps with the help of a JavaScript library, which is a collection of ready-made JavaScript code.

Jquery is a top example of a JavaScript library. Other examples of JavaScript libraries and frameworks include:

  • Redux
  • D3. js
  • jQuery UI
  • React
  • Three.js.
  • Express
  • Angular
  • Spring

So from the explanation so far, you can pinpoint that jQuery is a JavaScript library. Since its launch, it has been one of the most popular JavaScript libraries. It offers helpful features and conceals some inconsistencies between JavaScript implementations in various browsers.

Let’s look into the history of JavaScript and jQuery.

History of Javascript 

Early in the 1990s, when the term “JavaScript” first surfaced, Netscape Navigator and Internet Explorer were the two most popular browsers. The necessity for browsers to react to user commands arose at that point. JavaScript was to solve the problem.

In 1995, Brendan Eich, a Netscape employee, created JavaScript, although LiveScript is what he called it during its launch. Later, the script underwent a renaming to capitalize on Java’s fame (another well-known programming language at the time).

JavaScript upon its launch helped programmers to assemble components and automate interactions between browsers.

 But the challenge with Javascript during this time was that it was browser specific.

Because various people were using different browsers, different browsers might not read the same JavaScript code in the same way. The ability to design Javascript code that would function one way in Firefox but another in Internet Explorer was starting to pose a serious issue for web developers.

To help the situation, some browsers were updated more frequently and added new features of Javascript faster than others.

JavaScript (ECMA-262) became an ECMA standard in 1997, and ES2 and ES3 followed in 1999. ES4 and ES5 were released in 2008 and 2009, respectively. Then, from 2011 to 2014, ES5 was supported by every browser. When ES6 was eventually launched in 2015, complete support for all browsers remained until all browsers had fully adopted it by 2018.

Over the past three decades, JavaScript has existed in some capacity, and there are resources available for new users to get started with it.

With 67.7% of people using it, JavaScript will remain the most popular programming language, according to a StackOverflow study from 2020. (for the 8th year running).

History of Jquery

Web developer John Resig became dissatisfied with how challenging it was to create cross-browser JavaScript and made the decision to create his own JS library to address the issue. John Resig first developed JQuery at BarCamp NYC in January 2006, drawing inspiration from Dean Edwards’ previous cssQuery library.

Richard Gibson is currently in charge of Sizzle, the jQuery selection engine, and Timmy Willison is currently in charge of its upkeep. The syntax of JQuery is made to make it simpler to move about a document, pick DOM elements, build animations, manage events, and create Ajax apps.

The online development community’s fondness for jQuery led to the emergence of a strong ecosystem of websites, plugins, and frameworks in the late 2000s.

Developers can also build plug-ins using jQuery on top of the JavaScript library. This enables developers to make abstractions for high-level, theme-able widgets, complex effects, and low-level animation and interaction. JQuery was designed so that it would  handle the differences between different Javascript interpreters

Pros of JQuery

In addition to simple expressions like picking components based on their ids or classes, jQuery also supports sophisticated expressions like selecting elements based on their connections to other elements. Comparatively speaking, JQuery is much simpler to use than other javascript libraries and basic javascript. Along with having a straightforward syntax, it also uses a lot fewer lines of code to accomplish the same result.

In contrast to other JavaScript libraries, JQuery allows you to carry out a vast array of functions. It makes it simple to create Ajax templates and allows for a more streamlined user interface where actions can be taken on pages without requiring a page reload.

Cons of JQuery

Although JQuery has a sizable library, its capability may be constrained depending on how much customization you need for your website, making the use of raw javascript necessary in some circumstances.

Finally, jQuery isn’t a comprehensive solution, unlike other libraries. Another product, such as jQuery UI, is necessary to build a whole application (see the article after this one). It’s important to realize that using jQuery will make your site more modular and dependent on more libraries.

Best way to Learn Javascript and Jquery?

As a beginner, you must learn JavaScript and jQuery utilizing your best-learning strategy. We all have different learning styles: videos, books, or hands-on practice. So what are some of the best ways to learn JavaScript and jQuery? 

1. Books

A common way to learn JavaScript is through books. There are free ebooks and PDFs available for this purpose, and you may purchase these books from an offline or online marketplace.

2. Videos

Videos are a different way to learn JavaScript and jQuery. JavaScript on YouTube, one of the most famous video platforms where you can quickly access free practical video courses, is a terrific place to start learning javascript.

3. Online Games

Playing online code challenge games is a terrific choice if you’re looking for a fun and exciting way to learn JavaScript. These games can help you master new skills and hone your problem-solving abilities in jQuery and JavaScript. You can learn ideas from these games that will help you better grasp how to solve programming problems using JavaScript and jQuery.

4. Build Projects

Starting and finishing several projects is one technique to ensure you comprehend what you learn from the abovementioned strategies. Building projects will aid in your understanding of many JavaScript libraries, of which JQuery is an example.


Is Jquery dead?

No, for some short tasks, such as creating interactive banners, landing pages, etc., jQuery is still handy.

Is Jquery still worth learning in 2022?

Just keep in mind that you should be familiar with the fundamentals of jQuery because there are still use cases for it.  But you should avoid concentrating on jQuery in 2022, although jQuery’s ability to alter the DOM with less code is now its main benefit.

Is Javascript Better than Jquery?

JavaScript is directly handled by the browser and reduces the cost that JQuery truly has. It is faster for DOM selection and manipulation than jQuery, although JQuery runs quickly on contemporary machines and browsers. To execute in a browser, JQuery must be translated into JavaScript.

Why Was JQuery Originally Designed?

Because different Javascript interpreters have varied capabilities, jQuery was created to address these variances.

Is jQuery Still Widely Used?

No, certain factors affect its use. The first is the standardization of Javascript interpretation across browsers. Secondly, web developers’ constant use of “frameworks” like Angular, Ember, React, or Vue.

Javascript vs Jquery: Which is Faster? 

JavaScript functions execute faster than jQuery operations, notably for DOM selection and manipulation, as JavaScript is handled directly by the browser and reduces the overhead that JQuery genuinely has. JQuery performs swiftly on modern computers and browsers.


The fact is that JavaScript, with its extensive libraries and frameworks, will make programming intriguing for you. But knowing when and how to use these Javascript libraries or frameworks will make you a concise, fast, and senior web developer in a short time.
