What is jQuery?
jQuery is a free JS library that makes it quicker and easier to build JS webpages/web apps. -
How does it help us as developers?
You can write powerful JS apps using fewer lines. jQuery library is great for things like animations, Ajax requests, DOM manipulation, image effects and UI elements. It also lets you easily write cross-browser JS code. -
Why do we have 2 version of jQuery - minified and uncompressed?
The minified js file has all comments, whitespace and other unnecessary characters removed from the js file, so it takes less space to save. Therefore the minified version is the version to place on the JS webapp/webpage, as itâs much quicker to download.
The uncompressed js file is easier to read and modify, but it takes up more space to save.
- jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps.
- It helps us with things like animations, Ajax requests, DOM manipulation, image effects, and user interface elements, and lets us easily write cross-browser JavaScript code.
- minified is designed to load faster on webpages by removing documentation and whitespace. Uncompressed is designed for readability for developers.
-
In Javascript, jQuery is a popular library that allows a quicker and easier way to build webpages and web apps. It is a library made up of quick links of prewritten code that come in form of a single .js file. You embed these lines of code in your webpage for the browser to read and call the function from the library.
-
jQuery is a free library that allows code to be shared but specifically helps with user interactiveness, writing cross-browser code, and offline functions. Having a tool like this allows for code and web development to advance quicker.
3.Minified .js files are the versions of code you will place on your site that have all nonessential characters removed which makes the code quicker to load but harder to read and edit. Uncompressed is a larger file and is easy to read and modify.
1.What is jQuery?
jQuery is a library that is used to makes web pages easier to build. It has a lot of functionality to help us build better.
- How does it help us as developers?
With jQuery we can easily write one line of code which would have taken about 20 to 30 lines of code. It helps us by taking away the nitty gritty details in order for us to build more complex systems, in shorter time frames.
- Why do we have 2 version of jQuery - minified and uncompressed?
uncompressed is the bigger file which have all the details. It is easier to read and modify.
minified is a smaller compact size which all the white spaces and comments are removed. All the unnecessary items or details have been removed to make it smaller.
-
jQuery is an open-source library that consists of various functions to assist JavaScript developers with creating interactive web pages using a faster and easier approach.
-
Using jQuery provides access to functions that can be used to write powerful JavaScript apps and interactive animated effects. Some of the advantages include:
- Adding animated effects to elements: HTML elements can be easily modified to have engaging effects such as fading, sliding, and expanding/contracting.
- Making XML (Ajax) requests: Ability to request additional data from the Web server without reloding the page.
- Manipulating the DOM: The content of the web page can easily be added, removed or reordered.
- Creating image slideshows: Slideshows can be added for creating an interactive web page or for aesthetic purposes.
- The uncompressed version is created for developers to study the code as it contains comments explaining parts of it. The minified version is created for common usage where all comments and explanations have been removed. Due to this, itâs size is smaller, allowing visitors to download quickly.

jQuery is a javascript library. -
How does it help us as developers?
It allows you to call commonly needed functions without having to write out a large amount of code. It also handles browser differences on its end. -
Why do we have 2 version of jQuery - minified and uncompressed?
The uncompressed version is easier to read, while the minified version is quicker to load.

What is jQuery?
jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps. -
How does it help us as developers?
With jQuery you can write a single line of code to achieve what would have taken 10-20 lines of regular JavaScript code. -
Why do we have 2 version of jQuery - minified and uncompressed?
Because of the size of one version versus the other. Uncompressed has 160kb and minified has 23kb.
1- Jquery is a free, available online JS library
2- we donât have to re write something already done by pro dev. it is browsers proof
3. a light one for speed a heavy one for clarity
- It is a the most popular JavaScript library.
- It provides us with usable code that adds lots of functionality across various browsers and is free to download and use.
- There are two versions, as one (uncompressed) is more for the programmer to understand whats going on, as it contains comments and the second (minified) is what should be used on your website, as it is stripped of comments, whitespace, etc., and is a much smaller file, thereby loading faster for the user of your website.
-
jQuery is an open-source javascript library
-
By providing âbuilt-inâ functionality, reducing the amount of code that has to be written
-
Minified is used so that a webpage will only load a smaller file compared to the uncompressed version which has comments meant to help developers understand and use the library
1 - jQuery is a free-to-use library that enables programmers to re-use pre-written code when creating web apps and web pages.
2 - jQuery can allow you to quickly add code to projects, saving you from having to write out lines of code, where jQuery can allow you to use a single line of code to achieve the same goal as having to write 10-20+ lines of code.
3 - An uncompressed file is easy to read and modify, but are larger in size - taking up around 160kb in size. A minified file removes comments, whitespace and unnecessary characters - reducing the size of the file to aorund 23kb. However, the code in these files are harder to read, but when used in web pages it will allow users to download the page quicker than with an uncompressed file.
-
JQuery is a library written in JavaScript enabling you to manipulate and build powerful web pages and apps, in a quick and easy way. It is a stable and tested library.
-
As developers you can use JQuery to write apps in fewer lines of code, which would normally take many lines of JavaScript. A productive development tool full of features.
It enables dynamic manipulation of animation, image effects, DOM and user input/output
It provides for cross browser incompatibility by handling browser differences within JQuery.
The library is a single downloadable file.
- Versions JQuery.
Uncompressed - a fully documented version which can be read/modified and typically size of 160KB.
Minified - A smaller non legible version typically 23 KB in size with all comments, white spaces and unnecessary characters removed to compact itâs size. This makes the file faster to download without loss of functionality.
-
jQuery is a collection of functions in a .js file that have become public domain which allow a programmer to call jQuery functions with an attribute instead of writing many many lines of code.
-
jQuery saves time and headache as developers because you can concentrate on the more customized tasks in a specific project instead of having to take time to make make words scroll across the screen as an example.
We have to versions of jQuery. The uncompressed is for ease of reading for the developer to scan and figure out where to make changes or understand the logic if needed. The compressed version takes out all unnecessary bits making the file smaller and more quickly available when called by a webpage.
What is jQuery?
jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps. Often with jQuery you can write a single line of code to achieve what would have taken 10-20 lines of regular JavaScript code.
jQuery is itself written in JavaScript, and comes in the form of a single .js file that you link to from your webpage. Your JavaScript code then accesses the library by calling various jQuery functions.
How does it help us as developers?
jQuery makes it easy to write powerful JavaScript apps and create eye-catching animated effects rivalling those of Flash movies. Amongst other things, jQuery is great for:
- Adding animated effects to elements. jQuery lets you easily add effects such as fading in/out, sliding in/out, and expanding/contracting.
- Making XML (Ajax) requests. These use JavaScript to request additional data from the Web server without having to reload the page.
- **Manipulating the DOM You can easily add, remove, and reorder content in the Web page using just a couple of lines of code.
- Creating image slideshows. You can use jQuery effects to build nice animated slideshows and lightboxes.
- Making drop-down menus. jQuery makes it easy to create multi-level dropdowns with animations.
- Creating drag-and-drop interfaces. Use jQuery to build a page with elements that can be repositioned or reordered simply by dragging and dropping.
- Adding power to forms. With jQuery you can easily add complex client-side form validation, create auto-complete Ajax text fields that pull data from a server-side database, and so on.
Another of jQueryâs strong points is that it makes it easy to write JavaScript that works on many different browsers. Incompatibilities between popular browsers such as IE, Firefox and Safari mean that you often need to write different chunks of JavaScript code for each browser. With jQuery, however, you just call the appropriate jQuery function and let jQuery deal with making the code run on different browsers. Nice!
Why do we have 2 version of jQuery - minified and uncompressed?
The jQuery library actually comes in 2 forms:
-
The uncompressed .js file is easy to read and modify, but itâs around 160kb in size (at the time of writing).
-
The minified .js file has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into a mere 23kb. Although you canât easily read the code, this is the version youâll want to place on your site, as itâs much quicker for visitors to download.
- It is a JavaScript library which contains many functions pre-written that can be integrated into websites to make them more interactive.
- It allows us to save time rebuilding each function but also enables cross browser functionality. It also gives us the ability to build on past functions to create more interactive and dynamic websites.
- The uncompressed it easier to read and decipher however the larger size could slow down functionality. The minified version allows the same use with less readability but faster downloads.
What is jQuery?
- jQuery is a javascript file âlibraryâ available on the internet that is downloaded to each browser
visiting a site using it.
- It is a free opensource MIT/GPL dual license.
- helpful for menus, animations, ajax requests, DOM manipulation, image affects, and elements modifications.
- Cross-browser compatibility built-in⌠(which used to be a PAIN due to IE mostly with incompatability between versions).
- simplifies your codeâŚ
How does it help us as developers?
- Simplifies code
- Well tested for bugs/security
- Cross-browser compatibility built-in
- Simplifies tasks like menus, animations, ajax requests, DOM, image effects, etcâŚ
Why do we have 2 version of jQuery - minified and uncompressed?
- The uncompressed is easier to read, has comments.
- The minified - is stripped of comments and is smaller so that it is less for downloads to each browser.

What is jQuery?
jQuery is a javascript library that allows for simpler web page creation and web app development. -
How does it help us as developers?
Can easily add interesting animations, Can minimize network delay through using Ajax to avoid web page reloading. Can manipulate the DOM with far fewer lines of code. Can easily create drag and drop interfaces. Can add complex form validation. And very importantly it can make code run on many different browsers with little difficulty. -
Why do we have 2 version of jQuery - minified and uncompressed?
Minified is the compressed version of jQuery with whitespace etc removed and uncompressed shows whitespace and comments. Uncompressed allows for programmers to explore and understand the code more easily while compressed allows for better network speed.
-
What is jQuery?
jQuery is a library for javascript which makes it easier to write code that is compatible across multiple browsers and is also packed with lots of built in functionality such as animations, ajax, formatting etc. -
How does it help us as developers?
It makes writing code faster as we dont have to rewrite functionality from scratch. -
Why do we have 2 version of jQuery - minified and uncompressed?
uncompressed contains comments and is formatted so that humans can read and easily understand the code. minified has been compressed and formatted with only what the computer needs to run the code, this makes the file faster to load and run so offers better performance.
- What is jQuery?
jQuery is biggest js library that help developer to build js apps much faster - How does it help us as developers?
Its already written code soo developer dont need to make their own version of code that would be larger size anyway - Why do we have 2 version of jQuery - minified and uncompressed?
minified version is compressed version that is not that readable as uncompressed version but its much smaller and do the same job soo almost every site uses smaller versions because page loads faster with that
*** What is jQuery?** It is a large database of apps and add-ins also written in JS link our programs to.
*** How does it help us as developers?**. It is already written functions and plug ins. We then donât have to waste time building these functions that are synonymous with most websites like personal data and passwords for instance. We just provide a link from our program to the library and use what we need. ! line to code to the library rather than 20+ lines of our own code. The library works on every type of browser.
*** Why do we have 2 version of jQuery - minified and uncompressed?** 1 is easy to read and modify, but is file size is very large. The other is compressed, smaller, and therefore is faster to load.
