    1. jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps.
      2.How does it help us as developers - With jQuery you can write powerful JavaScript apps using fewer lines of code. jQuery is great for things like animations, Ajax requests, DOM manipulation, image effects, and user interface elements. jQuery lets you easily write cross-browser JavaScript code.
  2. 2 version of jQuery
    a. The uncompressed.js file is easy to read and modify, but it’s around 160kb in size (at the time of writing).
    b. * 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 can’t easily read the code, this is the version you’ll want to place on your site, as it’s much quicker for visitors to download.

Reading Assignment - jQuery

  1. What is jQuery?
    2. jQuery is the most popular JavaScript library for building websites. It is open source under MIT and GPL licences.

  2. How does it help us as developers?.
    3. With jQuary developer can easily create animated and nice looking Websites. jQuary is also compatible for most common browser so you don't have to rewrite chunks of code for different browser.

  3. Why do we have 2 version of jQuery - minified and uncompressed?.
    4. jQuery minified is a compressed version of the library .js file. It should be used for your website as it is small in size. jQuary uncompressed is unlike the minified version bigger in size. It contains spacing and other unnecessary characters which makes it easy to read and edit.

#223
  • What is jQuery?

An external open-source JavaScript library with numerous functions and plugins that we can add to our code

  • How does it help us as developers?

Don’t need to re-invent code/functions and jQuery provides cross-browser compatibility

  • Why do we have 2 version of jQuery - minified and uncompressed?

Minified should be added to one’s site due to file size (small) but uncompressed is easier to read and edit.

#224

So what is jQuery exactly?

jQuery is a library that makes it quicker and easier to build JavaScript web pages 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 web page. Your JavaScript code then accesses the library by calling various jQuery functions. Hundreds of jQuery plugins are available to add even more power and functionality to your scripts.

Q: How does it help us as developers?

jQuery help developers by making it easy for developers to write powerful JavaScript apps and create eye-catching animated effects rivalling those of Flash movies. Amongst other things, jQuery is great for:

  1. Adding animated effects to elements. jQuery lets you easily add effects such as fading in/out, sliding in/out, and expanding/contracting.

  2. Making XML (Ajax) requests. These use JavaScript to request additional data from the Web server without having to reload the page.

  3. Manipulating the DOM. You can easily add, remove, and reorder content in the Web page using just a couple of lines of code.

  4. Creating image slideshows. You can use jQuery effects to build nice animated slideshows and light boxes.

  5. Making drop-down menus. jQuery makes it easy to create multi-level drop downs with animations.

  6. Creating drag-and-drop interfaces. Use jQuery to build a page with elements that can be re- positioned or reordered simply by dragging and dropping.

  7. 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.

Q: Why do we have 2 version of jQuery - minified and uncompressed?

A:

  1. The uncompressed .js file is easy to read and modify, but it’s around 160kb in size (at the time of writing).

  2. The minified .js file has all comments, white space, and other unnecessary characters removed from the file, squeezing the whole library into a mere 23kb. Although you can’t easily read the code, this is the version you’ll want to place on your site, as it’s much quicker for visitors to download.

    How does it help us as developers?
  2. jQuery makes it easy to write powerful JavaScript apps & create eye catching effects. It uses fewer lines, it’s also used to create cross-browser JS code.
  3. The uncompressed js file is easy to read & modify, but is a big file approximately 160kb. The minified version is smaller, quick to load, but can’t be read as easily.
#227

  1. jQuery is a library that allows users to more easily build apps and webpages using javascript.

  2. It helps developers by allowing them to build things more efficiently. What would take 20 - 30 lines of code can be done with one using jQuery.

  3. The main reason for the difference is the size of the .js files. Uncompressed .js files includes comments and whitespace which makes it easy to read and understand, and makes it useful for developers for reviewing the code. It typically has s size of around 160kb. Minified .js does not include comments and other unnecessary characters which makes it lighter at around 23kb. Because of its smaller size this is the version that is typically used on websites as it lets visitors download faster.

1.What is jQuery?
-jQuery is a library that makes it easier for developers to design powerful apps through creating animation effects, adapting Javascript code to different web browsers and making 10-20 lines of code compressed down to single lines of code.
2. How does it help us as developers?
It makes it easy to translate javascript code through different browsers that would require a change in certain syntax when the jQuery does that for us. It also helps us create animation for the viewer to engage with on the webpage.
3. Why do we have 2 version of jQuery - minified and uncompressed?
Minified: has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into a mere 23kb. Although you can’t easily read the code, this is the version you’ll want to place on your site, as it’s much quicker for visitors to download.

Uncompressed:is easy to read and modify, but it’s around 160kb in size (at the time of writing).

#231
  1. What is jQuery?
    jQuery is a JavaScript library that makes building web apps quicker and easier to develop web pages.
  2. How does jQuery help developers?
    Developers leverage jQuery to aid in many everyday JavaScript tasks such as animation, DOM selection. There are many useful jQuery based plugins as well.
  3. Why do we have 2 version of jQuery - minified and uncompressed?
    The uncompressed version is for readability so we can understand what the code is doing for us. The minified version has the extra spaces removed to keep the file size as low as possible.

jQuery is a library that makes coding faster and easier to build things with js. jQuery helps us write js easier and faster than ever before. There are two versions because the makers of jQuery want to let you have a decision between faster and more efficient (minified) or a code that is easier to understand and easier to write at the cost of 137 kb (uncompressed). Both versions can be (sometimes have to) used for a certain type of program

#233
  1. jQuery is a free javascript library we can use.
  2. It has pre written functions that many of developers need today. There is no need to start from the beginning. Besides that, it also enables us to make a specific functionality in much shorter amount of lines than it would take if we only used javascript.
  3. Uncompressed version is larger in size but easily understandable, while minified version is smaller in size but harder to understand due to no spacing or extra comments. Minified is to be used due its smaller size.
#234

jQuery is a free JavaScript library. Using fewer lines of code, we can have the end user’s browser fetch from the minified our animations, give the user more elaborate forms to create a better experience, better the overall experience of using our webpage or app. We should stick with using the minified, which is far smaller than the uncompressed- no comments, no whitespace nor unnecessary characters, for the end user experience. The uncompressed is more for developers to review.

  1. What is jQuery?
    A javascript librarym which makes developing webpages easy

  2. How does it help us as developers?
    You need less lines of code while doing the same things.

  3. Why do we have 2 version of jQuery - minified and uncompressed?
    The uncompressed all the comments in the code, the minified not. The minified load faster, reason why you should add this one in your website. The uncompressed is handy to read and learn what the code is doing as developer.

#237
  1. What is jQuery?

jQuery is free JS library.

  1. How does it help us as developers?

It provides efficient and tested code, it is all done in fewer lines and makes sure it will be cross-browser.

  1. Why do we have 2 version of jQuery - minified and uncompressed?

There are two version, the bigger one, uncompressed .js file, with whole content whereas, the smaller one, minified.js, is without unncessesary characters, comments and whitespaces and the most important it is faster to load for browser.

#238
  1. JQuery is a library, written in Javascript. That contains a lot of useful code for making our page interactive and live without reloading it.
  2. As developers we can call functions that allows us to use animation, send requests to server, and change DOM(domain object model) without reloading the page
  3. In uncompressed all indentations and comments are in place for people to read and modify it, but it comes with a cost of disk space. Minified is a light version which contains only useful code and no other symbols and it is impossible to read but it lightweight and can do the job
#239

  1. jQuery is a the most popular library in JavaScript.

  2. How does it help us as developers?
    It´s helping, cause it´s more efficient a already complete code, which had been already tested and it´s less code to write.

  3. Why do we have 2 version of jQuery - minified and uncompressed?
    The uncompressed.js file is easy to read and to modify, but as disadvantage is very big(160 kb) so it will take time for the website to load it.
    The minified.js file is smaller (23kb), so it´s better to load this into the website. But as disadvantage the code is hard to read, cause all comments and unnecessary characters are removed.

#240

  1. It’s a free JavaScript library.

  2. It holds a vast collection of JavaScript code that can be reused however the developer needs. This saves massive amounts of time, and it makes the code appear less cluttered because it only requires one line to fetch something from jQuery instead of several lines for each function.

  3. A developer may simply need to incorporate jQuery on their website to give it certain functionality without slowing down the user experience, which is best suited for the minified file. However, if editing is necessary in order to give the code somewhat different functionality, the uncompressed file will allow this flexibility at the cost of holding a larger .js file.

#241

1 What is JQuery?
JQuery is a free downloadable javaScript library.

2 How does it help developers?
It’s a powerful tool that helps developers to deploy useful functions into websites and apps with fewer lines of code than what would typically be and handles cross browser javaScript code in any browser.

3 Why do we have 2 versions of JQuery?
There are 2 versions of JQuery. Uncompressed JQuery which is easily readable and amendable but renders large storage space and minified JQuery which is not easily readable and does away with comments and unnecessary characters utilising much lesser storage space. Despite it’s hard readability attributes it’s the version most used.
