Difference between javascript and jquery: The comparison you should know

Javascript and Jquery both are powerful and are used in web development. Both of them are used for the same purpose are to make the web page interactive and dynamic. People may wonder that why these two separate concepts? Thus, in this article, we – ArrowHiTech will go through what are the key differences between javascript and jquery

What is Javascript?

JavaScript là gì?

JavaScript (JS) is a dynamic programming language. It is an interpreted language. Moreover, it has nothing to do with the Java programming language. Furthermore, as the name suggests, JavaScript is a scripting language.

Firstly, you can use JavaScript to create slideshows, image galleries,… on your website. In addition to these, you can also use it to create games, 3D graphics, and data-driven applications.

Moreover, you don’t need any tools to support JavaScript. This is because it considered the language of the web since its inception. Finally, it runs in all modern browsers without any additional plugins.

What is Jquery?

JQuery is a JavaScript library. Firstly, it helps with HTML event handling, document browsing. Besides, it makes the interaction processing for Ajax simpler, faster and more efficient. Furthermore, it design for a specific purpose. As a result, that will handle the HTML client-side script.

However, JQuery is not a language. Instead, it’s very well-written JavaScript code. It comes with a number of built-in features and functions. This makes it easy and efficient for developers to use. Best of all, it’s great at handling cross-browser issues without requiring too much code. Moreover, developers do not need to know new syntaxes to implement JQuery. This saves the time and effort that goes into writing many lines of code.

Why jQuery is created and what are the special capabilities of jQuery?

In JavaScript, we have to write a lot of code for basic operations while with jQuery the same operations can be done with a single line of code. Therefore developers find it easier to work with jQuery than with JavaScript.

  • Though JavaScript is the basic language from which jQuery has evolved, jQuery makes event handling, DOM manipulation, Ajax calls much easier than JavaScript. jQuery also allows us to add animated effects on our web page which takes a lot of pain and lines of code with JavaScript
  • jQuery has in-built plugins to perform an operation on a web page. We just have to include or import the plugin into our webpage to use it. Thus plugins allow us to create abstractions of animations and interactions or effects.
  • We can also make our custom plugin with jQuery. If we require an animation done on a web page in a certain way, we can develop a plugin according to the requirement and use it on our web page.
  • jQuery also has a high-level UI widget library. This widget library has a whole range of plugins that we can import on our webpage and use it for creating user-friendly web pages.

Difference between javascript and jquery.

Let’s following table will show you the differences between javascript and jquery.

Sự khác nhau giữa Javascript và Jquery
Features JavascriptJquery
ExistenceJavaScript is an independent language and can exist on its own.
JQuery is a JavaScript library. It still depends on JavaScript. Jquery must be converted to JavaScript to be able to interpret and run it.
Language JavaScript an interpreted language. This is a combination of ECMA script and DOM
It uses resources of JavaScript to make things and task simpler and easier. It has only the DOM

JavaScript uses more lines of code because we have to write our own codejQuery uses fewer lines of code than JavaScript for the same functionality
JavaScript code is written inside the script tag in a HTML page:
<script> </script>
We need to import the jQuery from CDN or from a location where the jQuery library is downloaded in order to use it. jQuery code is also written inside the script tag on the HTML page.

AnimationsWe can make animations in JavaScript with many lines of codeIn jQuery, we can add animation effects easily with fewer lines of code.
JavaScript can be difficult for developers. Because it can take several lines of code to achieve a functionjQuery is more user-friendly than JavaScript with few lines of code

CompatibilityDevelopers write their own code to handle multi-browser compatibility in JavaScriptjQuery is cross-browser compatible. Developers do not need to worry about multi-browser compatibility issues
Event handling, Interactivity, and Ajax callsAll these can be done in JavaScript. However, we may have to write many lines of code.All of these can be done easily with jQuery. Moreover, we don’t have to write many lines of code. In jQuery, it’s easier to add interactions, animations and make ajax calls.

Which should be used JavaScript or JQuery?

JavaScript is a language for web development. jQuery is a library derived from JavaScript. So, both are important in web development.

For faster web development we should use JQuery. Because it handles browser errors and passes library functions faster. For early product versions, you can start with JQuery as debugging time will also be reduced. Then you can switch to JavaScr.
