1. What is JQuery?
JQuery is a library that makes it quicker and easier to build JavaScript web pages and web apps, using less code.
2. How does it help us as developers?
It helps save time and helps us write less code while accomplishing more.
3. Why do we have 2 versions of JQuery - minified and uncompressed?
The minified version is a smaller file size that is less readable to a human, but executes faster in production on a web page for the user.
a library that makes it quicker and easier to build JavaScript webpages and web apps
with jQuery you can write a single line of code to achieve what would have taken 10-20 lines of regular JavaScript code.
The size of the uncompressed file is large, making it cumbersome in some instances.
What is jQuery?
It is a Javascript library that makes it easy to add powerful functionality to websites, without having to write the Javascript code from scratch.
How does it help us as developers?
jQuery is a huge time saver and it allows us to concentrate on solving specific higher-level problems instead of having to write tons of code that has already been written before â and itâs freely available.
Why do we have 2 version of jQuery - minified and uncompressed?
Uncompressed jQuery files make it easier to understand (and therefore modify) its code because it includes comments, white space and other unnecessary characters that take a lot of space. Minified jQuery files have all the non-essential information removed and thus are much smaller in size, and are served much faster and efficiently. Itâs a good idea to use the uncompressed version to study and understand the code, but then place the minified version on the site.
1/Jquery is a javaScript Library that enable to add multiple functions and code in much simpler way
2/ You can easily use and add functions that wont need to be re written in various browsers- its multu browser usable-
3/The uncompressed version it to understand its use and or ready line by line whereas the minified version is for instant application and has no spaces or useless presentation added- its for direct application with no comment spaces etc etc its RAW
What is jQuery? : jQuery is a free JavaScript library
How does it help us as developers? : With jQuery you can write powerful JavaScript apps using fewer lines of code.
Why do we have 2 version of jQuery - minified and uncompressed? : One is easier to read, the other is smaller and easier to load
JQuery is a javascript library.
It helps us to speed up our development by allowing us to re-use code instead of write it ourselves. It also has unique functions we can use, such as adding animated effects etc.
Uncompressed comes with comments and other information that has no effect on the code. This helps us as developers to see whats going on.
But the uncompressed file is larger and will make the page slower to load. This is why we used the minified version.
What is jQuery?
Itâs a library that makes it quicker and easier to build JavaScript web pages and apps.
How does it help us as developers?
It makes it easier to write powerful JS apps, and creates eye catching, animates effects.
Why do we have 2 Versions of jQuery - minified and uncompressed?
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.
What is jQuery?
A library of pre written scripts that an easily be added to your program.
How does it help us as developers?
It saves time and effort, using just a few lines you can add the already written script.
Why do we have 2 version of jQuery - minified and uncompressed?
Minified is just the source code in a compressed state, making it smaller to download,
whilst Uncompressed is the full file with spacing making it easier to read, but making
1 jQuery is a library makes it quicker to write JavaScript code. It shorten the amount of code you need to execute the same result.
2 Write powerful JavaScript apps with great animations. Creating drop-down menus, drag-and-drop interfaces, image slideshows and so on.
3 Minified is less kb in size (23kb), faster for visitors to download. Uncimpressed is easy to read and modify, but is 160 kb in size.
What is jQuery?
It is the most popular JS based library, which contains a whole lot of functions that helps us save a lot of time when programming.
How does it help us as developers?
For example, instead of creating and typing a lot of code and lines that all ready exist, we can invoke those functions by simply calling on them with a single line of code. This has several benefits. The code becomes much more readable and cleaner, and you save a lot of time and code while doing so.
There are so many useful functions that are great for web or app developing. Besides that you can also add plug-ins to add more functions/power to your website/application.
Why do we have 2 versions of jQuery - minified and uncompressed?
The difference is that the minified is a package of 23kb at the time of writing, with all the code squeezed in and all spaces and comments removed, for a smaller packet and quicker upload/download. The uncompressed version is more readable, has comments,spaces and is easier to modify. Its a package of 160 kb at the time of writing.
Itâs a library that contains open source code and files, free to download and use, and is dual-licensed under the MIT and GPL licenses.
It is quicker and easier to build JavaScript webpages and web apps. JavaScript code then accesses the library by calling various jQuery functions.
With jQuery you can write powerful JavaScript apps using fewer lines of code.
for things like animations, Ajax requests, DOM manipulation, image effects, and user interface elements.
The uncompressed .js file is easy to read and modify, but itâs around 160kb in size (at the time of writing) which takes longer for user to load the page.
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.
What is jQuery?
Itâs an open source library for JavaScript
How does it help us as developers?
It helps by providing free building blocks or programmes for commonly used aspects of programming in JavaScript, therefore it saves a lot of time and effort.
Why do we have 2 version of jQuery - minified and uncompressed?
Uncompressed provides the same code as minified but contains comments and spaces so that it is more readable and understandable for devs. Minified takes all of these comments and spaces out so it is pure code and a much smaller file for fast downloading on the client side.
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.
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
Making XML (Ajax) requests
Manipulating the DOM
Making drop-down menus
Adding power to forms

2. It saves us a heck of a lot of time
3. The first version has is easy to read and is about 160kb/ the second version has all the comments and whitespaces removed. Although you cant read the code its the version you want to place on the website.
1: jQuery is library with enhancements for java script
2: JQuery makes it easier to build in JS because you can reuse code that is found in the library
3: minified is a smaller version that is good for downloads
Uncompressed version is more extensive and easy to read and modify
